It is not known that coal was recognized by the Indian in Kentucky, other than for the occasional use of cannel coal for the carving of trinkets. Yet it occurs in abundance in the region crossed by the Warrior's Trail from Cumberland Gap northeast to the mouth of the Little Scioto River. The first recorded discovery is that by Dr. Thomas Walker on April 13, 1750.1 He had entered the state at the head of a small party through Cumberland Gap (Cave Gap) and found coal a few miles to the north.

The first record of coal production in the state is that of 328 tons mined in 1828 (Rice, 1922). Gradual development followed to 1907 from which year on the industry expanded rapidly as a result of: (a) the introduction of improved mining machinery, (b) the building of railroads into virgin territory of eastern Kentucky about 1912, (c) the expansion of the by-product coke industry and the suitability of much of eastern Kentucky coal for this use, and (d) a somewhat lower price than in the unionized competitive fields.

|Coal-producing districts of Kentucky|
As indicated in plate LXXIII, figure 1, for the past decade Kentucky has alternated with Illinois in third and fourth position as a producer and is exceeded in tonnage produced by Pennsylvania and West Virginia. Development took place earlier in the western Kentucky field than in the eastern because of greater accessibility—a matter of topography and the Ohio River. As pointed out in an earlier chapter, the rugged topography in the vicinity of the Pottsville Escarpment in the west and the Pine Mountain-Cumberland Mountain region in the east, together with the greater relief and more rugged landscape of the eastern field as a whole, constituted a barrier to transportation and development. In spite of its somewhat superior coal and more of it, not until 1911 did production from the eastern field surpass that of the western.

SECTION B—EASTERN COAL FIELD
The eastern field constitutes a part of the Appalachian Coal Field and includes all or parts of 37 counties, totaling about 10,400 square miles. The bulk of production comes from 17, with Harlan, Pike, Letcher, Perry, Floyd, and Bell counties leading in the order given (pl. LXXIII, fig. 2; pl. LXXIV, fig. 1). The coals are high in volatile matter, low in sulphur and ash, and relatively high in heating value. The highest grade coals are found in the easternmost region bordering the belt of Appalachian deformation. Here a maximum fixed carbon content and heating value is found and there is progressive decrease to the west and northwest.
|FIG. 1. Coal production in Kentucky by counties, 1910-1937 (Eastern District)|
|FIG. 2. Coal production in Kentucky by counties, 1910-1937 (Western District)|
An average of many analyses shows a heating value of about 14,000 B.T.U. (13,000 to 14,500) in the Harlan-Bell County region. This decreases to 12,000± along the western border of the field and is about the same in western Kentucky. In Illinois it averages around 11,000 B.T.U. and in Iowa 10,000 to 11,000. A sulphur content (marcasite) of less than 1 per cent in the eastern counties increases to 1 to 3 percent in the western counties. An outline summary of analyses by counties is given below.
The high quality is reflected in the fact that the coal from these three eastern Kentucky fields finds its way into nearly every state east of the tier of states capped by the Dakotas, excepting those east of Pennsylvania and West Virginia (Theis, 1926). This means that they invade the natural markets of the coals of Ohio, Illinois, Tennessee, and Alabama as well as those farther west in Iowa, Kansas, and Arkansas.
The main use is for by-product coke and illuminating gas. Investigations of the United States Fuel Administration in 1917 showed that 87 per cent of the northeastern Kentucky production, 52 per cent of the Hazard production, and 44 per cent of the production of southeastern Kentucky were suitable for the making of coke. On the other hand only 6.5 per cent, 13.7 per cent, and 17.9 per cent from these same regions were used for railroad fuel (Tryon, 1922).
The exploitation of the field is behind that of its neighbors. Some individual
fields such as Harlan (1911) and Perry (1911) are of relatively recent
operation. "While West Virginia has exhausted one-eightieth of her reserves of
coal (counting as reserves all seams of more than fourteen inch thickness)
Kentucky has exhausted only one-two hundredth (½%)" (Theis, 1926, p. 5).
Wentworth (1927) estimated the minable coal of the Middlesboro Basin to be
4,314,000,000 tons of which less than 2% has been mined.

* Albert Pierce: The Growth and
Overdevelopment of the Kentucky Coal Industry, 1912-1929,
Cannel coals2 were first mined near Cloverport on the Ohio River in 1855. Important deposits in western Kentucky are restricted to Breckinridge and Hancock counties. In eastern Kentucky cannel coal is widespread but commercial thicknesses are not of great extent, and it is commonly produced as a part of a major bituminous operation. The better known seams are3 the Cannel City coal (= Van Lear) of Morgan County, the Hunnewell cannel No. 4 of Carter and Greenup counties, the Abbott Creek cannel of Floyd County (Elkhorn No. 1), and the Chenoa cannel (probably = Bennett Fork = Harlan) of Bell County.
The Eastern Coal Field occupies the eastern flank of the Cincinnati arch and the section from Pine Mountain thrust fault eastward. Within the field the most prominent structure west of Pine Mountain is the broad syncline referred to as the Eastern Kentucky geosyncline by the Kentucky Geological Survey (plate XXXII). This down warp is responsible for the preservation of the youngest beds and this preservation of beds is greatly accentuated by the thinning of the Pennsylvanian section to the north in Boyd and Lawrence counties and vicinity. Elsewhere over most of the field the Allegheny is present only on hilltops.
The region is maturely dissected, with thus a minimum of flat upland and bottom land. Hilltop elevations range from 1000 feet in the northeast to 3800 feet and more in the southeast. Local relief similarly varies from about 500 feet to 2000 feet plus.
The region is drained by the Big Sandy, Licking, Kentucky, and Cumberland rivers. None are open to navigation within the area of the coal field except the Big Sandy in its lower part. The valleys are of importance, though, in supplying access for railroads serving the fields. The Licking Valley has not been greatly used for this purpose and no field of consequence is located along it except that of the Cannel City coal area.
Northeastern Kentucky Fields (Big Sandy or Elkhorn field including mines in Boyd, Floyd, Carter, Johnson, Knott, Lawrence, and Letcher counties).—The mines on the west bank of the Tug Fork in Pike and Martin counties are considered a part of the Kenova-Thacker field of West Virginia. The greatest demand is from the by-product coke ovens, coal gas plants, and steel works using coal gas. The coal is too high priced for wide use as railroad fuel. Ten to 15 per cent is used for domestic fuel because it is hard and lumpy. Geographic position minimizes shipping to the east so the bulk moves north and west across the Ohio River. The coals are in classes two and three with respect to fusibility of ash.4
Hazard Field (Perry, Breathitt, and Lee counties).—The chief demand is from the retail trade (domestic) for the free burning and blocky Hazard coal. The coal is shipped to the north and west.
Southeastern Kentucky Fields (Bell, Clay, Knott, Laurel, McCreary, Whitley, and Harlan counties).—The uses are much as in the northeastern field except a larger proportion is used for railroad fuel, and smaller proportion for gas, by-product coke and general industrial purposes. The ash rates classes one and two in fusibility.
DISCUSSION BY DISTRICTS
Big Sandy Drainage5
Princess District (located in Boyd and Carter counties and served by the Chesapeake & Ohio Railroad).—This is the least important of the recog-nized and named coal fields. The Pennsylvanian section is thin and the coals in general inferior to those farther south. The principal producer is No. 7 (Coalton = Middle Kittanning) and No. 3 (Hitchens). Other commercial seams include No. 5, No. 6, and No. 8 (Jillson, 1924a), but these are not listed as producers in the more recent reports of the State Mine Inspector. No. 7 has a thickness of 42 to 46 inches, and No. 3 about 32 inches. The coals are relatively thin but proximity to the Ohio River has enhanced their value.
Kenova-Thacker District (located on the Tug Fork of the Big Sandy River in Martin and eastern Pike counties, and served by the Norfolk and Western Railroad. It is continuous with the coal-producing area adjoining in West Virginia).—Production is mainly from the Pond Creek = Freeburn = Warfield = No. 2 Gas seam which usually runs between 44 and 48 inches thick. The Thacker is a poor second but the name has been applied to so many seams that it has little stratigraphic significance, and production figures are correspondingly of little value. Other important production comes from the Alma and Winefrede seams.
Thicknesses listed give the Warfield 52 inches (40-78), Thacker, 51 inches (40-72), Alma, 44 inches (36-52), and the Winefrede, about 58 inches. Elsewhere in Martin County other coals of considerable thickness are found. The Peach Orchard coal is thick but is commonly ruined by partings. The Broas ranges from 52 to 85 inches and the Hindman is said locally to thicken to 5| feet.
Paintsville District (located on the Levisa Fork of the Big Sandy River in Johnson and Floyd counties and centering around Paintsville).—It is served by the Chesapeake & Ohio Railroad. Production comes from the several seams of the Upper Elkhorn. In the northern part of the field (mainly Johnson County) production is from the Millers Creek (Van Lear). To the south the Elkhorn No. 3 is the most important.
The Dwale, a lower coal (probably = Wayland) has been worked in the southeastern part of Johnson County and has a thickness of 42 inches over considerable area. About one-third of this county is listed as coal land. Several minor seams have also been worked in Floyd County.
The Millers Creek (Upper Elkhorn No. 1), where mined, has a thickness up to 63 inches and the usual range is from 42 to 46 inches. The Upper Elkhorn averages around 48 inches and has a maximum listed of 96 inches. Thicknesses of more than 50 inches are not uncommon.
Elkhorn District (located at the head of Levisa Fork of the Big Sandy River in Pike County and the North Fork of the Kentucky River in Letcher County; it is served by the Chesapeake & Ohio Railroad).—The bulk of production comes from the Elkhorn seam which has a reputation for by-product coking. There is considerable confusion in the differentiation of the Upper Elkhorn (Elkhorn) into the Elkhorn No. 1, No. 2, and No. 3, and uncertainty as to meaning when the term Elkhorn alone is used. Under the circumstances no attempt to differentiate them is made in plates LXXVI and LXXVII.
The entire area of Pike County, which includes both the Kenova-Thacker field on Tug Fork and the Elkhorn field on Levisa Fork, is classified as coal land.
Letcher County has workable coals throughout. In addition to those mentioned above Theis (1926) listed the Hamlin (up to 5 feet) in the central part; the Haddix, Flag, and Hindman (above 5 feet) in the southwestern corner; and the Shelby Gap (Lower Elkhorn—from 54 inches to 60 inches plus) in the Cumberland River drainage.
A number of mines in Letcher County list a thickness of 90 inches or more, and Theis (1926) mentions thicknesses up to 10 and 12 feet.6 An average of mined coals for Pike County gives 48 inches and for Letcher County 65 inches. In Pike County the Lower Elkhorn is an important producer. In Letcher County, in addition to the Elkhorn, No. 4 is an important producer, and the Whitesburg, Low Splint, No. 4 Rider, and High Splint less so.
Lawrence County.—Lawrence County has produced some coal. The upper Mercer (No. 4) is probably the most important in the county (Theis, 1926) with a thickness of 5 feet clean near Louisa. Other commercial coals include the Lower Mercer (= Elkhorn), and in the southern part of the county, the Peach Orchard and Richardson. No. 7 is listed in the report of the State Mine Inspector as a small and the only producer in 1928.
Licking River Drainage
Morgan County.—This county is important only in cannel coal production from the No. 2 = Van Lear seam centering around Cannel City, and was formerly served by the Ohio & Kentucky Railroad. About 10 per cent of the county is rated coal land.
Magoffin County.—Magoffin County is essentially undeveloped, but only about 25 per cent is coal land. Small production is listed but there is some confusion in the identity of the producing seam. The 1928 production from the Tip Top mine is listed as Hindman, and that for 1935 is listed as Millers Creek. The former is probably incorrect. The Fire Clay coal is widespread but thin (20 to 30 inches). Theis (1926) found workable thicknesses along the Breathitt County line and called attention to the Whittaker coal (approximate horizon of the Hazard No. 6) with a thickness of 42 to 54 inches plus in the extreme southern tip of the county at the main head of the Licking.
Kentucky River Drainage
Hazard district (located mainly in Perry County but including a little of southwestern Knott County on the North Fork of the Kentucky River).—The field was opened in 1912 with the completion of the Louisville & Nashville Railroad through Perry County. Main production is from the No. 4 (Fire Clay), No. 6 (Hazard), and No. 7 (Flag) seams. A little production is also listed from No. 9 and No. 5. Average thicknesses of the main producing seams are No. 7, 52 inches (40 to 56); No. 6, 56 inches (40 to 78); and No. 4, 38 inches (32 to 50).
Knott County is touched by railroad only at its northeast and southwest corners and, as a result, has been little developed. It lies low structurally and thus has a large exposed section of coal strata so that a large part of the county is listed as coal land. In addition to the coals of the Hazard field, the Whitesburg (36 to 46 inches) in the southern part, the Van Lear (36 to 48 inches), and Elkhorn (54 to 60 inches) on the Big Sandy drainage in the east are commercial coals.
Breathitt County (North and Middle forks of Kentucky River).—Breathitt County is essentially undeveloped except the area south of Jackson along the North Fork. The No. 4, No. 6 (Hazard), and No. 4 Rider are of importance in the order named with a total of only a half million tons (plus) production in 1928. The few mines reporting give No. 4 an average of 42 inches (36 to 46 inches), one mine reporting the No. 4 Rider 36 inches, and one the No. 6 (Hazard) 40 inches. Along Troublesome Creek the Flag coal has a thickness of 42 to 48 inches. The writer is unable to identify with assurance the "Jackson coal" listed in 1928 and responsible for more or less 21 per cent of the county's total. However, Miller (1919) listed the No. 3 or Elkhorn as the coal mined at Jackson so this presumably is the "Jackson coal."
Clay County (South Fork of Kentucky River).—Limited production is listed from the Horse Creek seam. This coal is probably the Lily = Manchester. Jillson (1924b) listed the Blue Gem as worked along with the Horse Creek.
Coals of commercial thickness are not widespread in the county. Along the western edge adjacent to Leslie County and again in the southeastern corner the Fire Clay coal attains a thickness up to 4½ feet. Locally, on Goose Creek the Howard coal is 4 feet thick.
Leslie County (Middle Fork of Kentucky River).—This county is undeveloped because of lack of railroad facilities. The distribution of com¬mercial coal seams is summarized by Theis (1926, p. 26):
"Probably the best coal land in this county centers around Hyden, near the center of the county, where the Fire Clay coal shows a thickness of 54 inches. From Hyden south, on the waters of Middle Fork this coal varies from 36 inches to less than 24 inches. Along the southern boundary the Hazard coal in places shows a good thickness. On Cutshin Creek, in the eastern third of the county, the Fire Clay shows a thickness of about 42 inches as far south as the latitude of Hyden and further south only about 30 inches. On the headwaters, against the Perry County line, the Hazard coal reaches thicknesses of about 4.5 feet. On the tributaries of Red Bird Creek of the South Fork of the Kentucky River, in the western portion of the county, the Fire Clay coal is variable, ranging from thicknesses of 42 to 48 inches in the north to less than 24 inches in the south."
Cumberland River Drainage
Cincinnati Southern District (McCreary County—served by the Kentucky & Tennessee Branch of the Southern Railroad).—Production comes from four seams in the lower few hundred feet of the Pennsylvanian. Most of the production is from the No. 1 (Hudson) and No. 1½ seams, and small amounts from the No. 2 (Beaver Creek) and No. 3 (Barren Fork) seams. Thicknesses of these seams are: No. 3—37 inches (34-40); No. 2—46 inches (44-48); No. 1½—44 inches (42-48); No. 1—44 inches (40-48).
Jellico District (Whitley County—served by the Louisville & Nashville Railroad).—Main production is from the Jellico seam with minor amounts from the Blue Gem which is usually mined along with the other. Both the Bacon Creek (Lower Blue Gem) and the Lily (Sharon) have been mined. The Jellico averages about 35 inches (30-40) in thickness. The Blue Gem averages about 2 feet. The lower coals mentioned under McCreary County (Nos. 1, 1½, 2, and 3) are present in thicknesses of 30 to 36 inches in the northwestern part of the county. In the section of Whitley County bordering Bell and Knox counties (Southern Appalachian Field) the Dean is of commercial thickness and extent.
Laurel County.—Laurel county has been a small producer for a good many years from the Lily seam. In recent reports of the State Mine Inspector the Laurel and Jellico are both listed, the former of which is the Lily. Some of the operations have been strip mining at East Bernstadt, Pittsburg, London, etc.
Southern Appalachian District (located in Bell and Knox counties and served by the Louisville & Nashville Railroad).—The field continues south-ward into Tennessee and to the north is continuous with the Harlan field. There are at least seven producing seams, of which the Straight Creek (Jellico of Knox County) and Mingo are outstanding. Small producers include the Harlan, Turner, Mason, Dean, and Hignite. The Straight Creek has been correlated in the past with the Blue Gem (Chisholm, Miller, and Theis, 1926), the Harlan (Jillson, 1924a), and the Jellico (Miller, 1919). This correlation by Miller was confirmed by the recent work of Wanless. It is used chiefly as a steam and domestic coal. Thicknesses listed are:
Hignite.................................... 45” (42-54)
Dean (Poplar Lick)................. 49” (32-72)
Mason................................... 42” (38-52)
Mingo (Creech)..................... 52” (48-60)
Jellico.................................... 43” (42-44)
Straight Creek....................... 36½” (30-42)
Harlan................................... 46” (40-48)
Turner................................... 60” (42-82)
Harlan and Benham Districts.—The Harlan District centers around the town of Harlan in Harlan County and the Benham occupies the northeastern end of the county. The region is served by the Louisville & Nashville Railroad and in part by the Southern. In the Harlan district, three-fourths of the coal mined comes from the Harlan seam. Other outstanding seams are the Kellioka (= Elkhorn = No. 3 = "C") and Wallins Creek (Dean). The Harlan is a hard block coal and is used for all purposes, including by-product coking. The Benham district relies mainly on the Keokee (= Kellioka). Harlan County leads the state in production. Thicknesses of producing seams are:
No. 10............................................................. 60"
No. 7 Middle Kittanning................................... 54"
High Splint,...................................................... 53" (40-62)
No. 5.............................................................. 44" (42-48)
Dean-Wallins................................................... 46" (39-60)
Low Splint....................................................... 46" (39-60)
Creech = "E"................................................... 42"
Darby. ........................................................... 37½”" (32-42)
Kellioka = Keokee = No. 3 = "C" = Elkhorn... 66" (34-96)
Harlan............................................................. 44½" (34-67)

SECTION C—WESTERN COAL FIELD
Of the dozen or so counties in the Western field which have produced coal, only five are important (one-half million tons per year or more)— Muhlenberg, Hopkins, Webster, Union, and Ohio. Of the coals No. 9 (Springfield of Illinois) is outstanding, with No. 11 (Herrin of Illinois) second. Other producing seams include the Bell (Owen No. Ib), No. 4, Empire = Mannington, No. 6, No. 7, No. 12, and No. 14.
The first commercial operation was a drift mine on the Green River in Muhlenberg County, opened in 1820 by William D. McLean. In 1825 several small mines were started in Daviess County (Burroughs, 1925). The Breckinridge cannel coal was mined in Breckinridge and Hancock counties as early as 1837 and in 1856 it was used for the distillation of oil.
The relatively early development of the western field was a matter of greater accessibility. Much of it is hilly but relief is much less than in the eastern field and slopes not so steep. Major valleys are commonly of great breadth due to extensive shale outcrop and Pleistocene alluviation. This has covered much of the outcrop so that core drilling is more commonly necessary than in the eastern field. Shaft mining is rather characteristic along with drift and some stripping operations. Little attempt is made to recover pillar coal, and recovery is about 60 per cent as against 75 per cent in the eastern field (Herbert, 1922). The coals of western Kentucky are chiefly in demand for steam raising, mainly by railroads, and also for domestic use. The amount of coal suitable for use in by-product coke ovens is small.
COMMERCIAL COAL SEAMS
Coals of the Caseyville Formation
There is little commercial coal in the Caseyville. The Nolin (Main Nolin) seam has been mined and used locally in the Nolin River region of Grayson and Edmonson counties and in northern Warren and southern Butler counties.
Breckinridge cannel.—This coal was mined in Breckinridge County and at Victoria in Hancock County, and for a while, beginning in 1856, was distilled for oil. It was a high grade cannel coal, varying from 2 to 4 feet thick. The last production is listed from 1898 and closing of the mines presumably was the result of exhaustion. Its correlation is uncertain as the Caseyville conglomerate is not developed in this vicinity. The coal occurs 25 to 40 feet above the base of the Pennsylvanian.
Coals of the Tradewater Formation
Commercial coal is produced from the Tradewater formation but not on a large scale. Seams mentioned in the reports of the State Mine Inspector include the Mannington = Empire, No. 4, No. 6, and No. 7.
The Mannington = Empire is the seam mined in northern Christian County and is the same as the Dawson Springs coal of southern Hopkins County. The names are taken from towns in these counties. A persistent limestone 30 to 45 feet above the coal is an important means of identification. For this limestone zone Glenn (1912) used the term Mannington limestone. It is at least near the horizon of the Curlew limestone of Webster and Union counties. In Hopkins County, where most extensively mined, the coal ranges from 40 to 54 inches thick. It is a bright clean coal without parting and with little sulphur (Glenn, 1912). Crider (1914a) mentioned a band of cannel coal up to 7 inches thick near the base in the Dawson Springs Quadrangle.
In more recent reports of the State Mine Inspector production in Christian, Muhlenberg, and Hopkins counties is listed from No. 6. As these are the same operations formerly mining this coal under the name of the Empire, etc., coals, apparently this seam has more recently been incorrectly identified as the No. 6. That seam was formerly mined at Dekoven and near Sturgis in Union County. The thickness is about 4 feet and it was commonly referred to as the "Four-foot" seam.
In the Owensboro region, involving Hancock and Daviess counties, the Hawesville and the Lewisport are the only coals that have been commercialized on any scale, though the Persimmon Run, Mason, Lead Creek, and Adair (40 to 44 feet above the Lead Creek coal) have at one time or another been worked locally. The Hawesville coal is lenticular and ranges up to 5 feet thick. It was mined in the vicinity of Hawesville for about 60 years and the region was an important mining center prior to the Civil War. It is a high grade coal, still the leading producer, though small, and pretty well worked out in the vicinity of the Ohio River. The Lewisburg coal averages somewhat thicker but slacks more readily. It has been of importance, second only to the Hawesville. Coals listed as No. 4 and No. 7 in state mining reports are very likely these seams.
No. 7.—This seam was formerly mined at Dekoven (Union County). Theis (1926) reported it as locally of workable thickness in Henderson County, and some production has been listed from it there, but not for the past seven or eight years.
In northern Butler and Logan counties small wagon mines have worked a number of local seams. These are indicated in section 5 of plate XXVII.
Coals of the Carbondale Formation
The Carbondale is the great coal-producing formation of the Western field. No. 9 and No. 11, supply the bulk of the coal.
No. 9 (No. 5 or Springfield coal of Illinois).—This is the standard coal of western Kentucky and the mining of it is attended with fewer troubles than any other coal in the region. While normally not attaining the thickness of No. 11, the absence of dirt slips, clay partings, and the uniformity of the coal make it the more desirable mining proposition (Crider, 1914). It is persistent, without parting, and uniformly 4 feet 8 inches to 4 feet 10 inches thick. Thicknesses of 6 feet 6 inches are listed from a number of mines in Hopkins County. The roof is good, and formed of black shale which often contains siderite or pyrite concretions (nig_er-heads) up to several feet in diameter. Some of the thinner seams such as the Bell, Empire, and Baker (No. 14) may show up better on analysis but are not so consistent. It is the main producer in every county of the Western field except an occasional border county exposing only the lowermost seams.
Ashley (1909a) has pointed out that this seam underlies some 25,000 square miles and is probably the most persistent coal in the eastern half of the United States. The famous Pittsburg seam underlies only 6,000 square miles or less.
No. 10.—This seam has been mined in a small way at Curlew and Dekoven in Union County. Elsewhere it is not known to be of workable thick¬ness. It is not listed as a producer in the 1928-1935 reports of the State Mine Inspector.
No. 11 (Herrin seam of Illinois).—The No. 11 ranks second in importance only to the No. 9. It is generally considered not quite so good, for it is somewhat dirtier, but analyses of the two are much alike. The ash comes mainly from the "blue band" and gob at the roof. (See below.) This, however, is "extraneous ash" and the coal can be cleaned. As a matter of fact, examination of many analyses shows No. 9 to be slightly higher in ash. Here analyses of clean samples are involved, and the matter is one of "inherent ash." No. 11 is less persistent and uniform in thickness, though it actually attains greater thickness and ranges up to 7 feet with an average of about 6 feet.
A characteristic section shows:
(e) top bench.
(d) "sulphur band," a quarter to half an inch of marcasite, 9 to 16 inches below the top.
(c) middle bench.
(b) "blue band," 1½ to 2 inches of blue grey clay,
(a) lower bench.
The blue band is a characteristic feature. Equally characteristic is the presence of the Providence limestone above, either forming the roof or separated from the coal by a few inches of gob, or up to 4 feet of black shale.
As with No. 9, it is too high in sulphur for a good coking coal.
No. 11 is mined in most counties of the Western field except those of the immediate border belt. Even here as in southern Hopkins, Muhlenberg, etc., the seam has been preserved in downfaulted blocks.
No. 12.—This is a small producer in Hopkins and Webster counties. It is rather unreliable in thickness though listed at about 6 feet where mined. Glenn (1922) found it low in sulphur, the lowest in fixed carbon and moisture, and highest in volatile carbon of the commercial coals. The roof is soft shale.
Coals of the Lisman Formation
With the exception of the Baker, a locally-developed thick coal near its base, the Lisman is normally barren of workable coal.
Baker Coal.—This coal was discovered in the course of drilling for No. 9 between Clay and Wheatcroft in Webster County and is known with certainty as a commercial coal only from this vicinity. It ranges from 4 to 7 feet in thickness and is low in sulfur and ash and volatile combustible matter. Because of a soft clay roof, 12 to 14 inches of coal must be left to form a roof.
The Baker seam was regarded by Glenn (1922) as the No. 14 and Nebo (Earlington vicinity). Wanless has more recently (1939) correlated it with No. 13. No. 14 listed from Hopkins County is apparently a little higher in the section.
