METHANE EMISSION FROM U.S. COAL MINES, A SURVEY

ABSTRACT 

This survey was conducted to determine the magnitude of the methane 

emission and control problem in U.S. bituminous coal mines. The resultant 

data indicate that the emission rate for any given coalbed depends primarily 

on the coal production rate and on mine depth, as well as on the nature of the 

coalbed and the surrounding strata. An excellent correlation was found between 

(1) the methane emission rate and (2) the product of coal production rate and 

mine depth for the mines in the Pittsburgh, Pocahontas Nos. 3 and 4, and the 

Illinois Nos. 5 and 6 coalbeds. 

The highest total emission rates found in U.S. bituminous coal mines were 

as follows, in million cubic feet per day: Monongalia County, W. Va., 39; 

Marion County, W. Va., 30.4; McDowell County, W. Va., 13.1; Washington 

County, Pa., 11.9; Greene County, Pa., 11.4; Buchanan County, Va., 21.6; 

Jefferson County, Ala., 10.3; and Franklin County, Ill., 6.6. 

1 Methane in air has long been a hazard to mine safety because of its 1 1 explosive qualities, and the Bureau of Mines has engaged in methane studies 1 

since its establishment in 1910. One of the earliest studies was actually 

begun in 1907 under the immediate supervision of Dr. J. A. Holmes, who 

subsequently became the first director of the Bureau of mine^.^ That study 

was made "to obtain information on the origin of the inflammable gases in 

coal and the conditions under which they occur." Data were obtained from the 

anthracite fields in Pennsylvania and the southern bituminous fields in 

Illinois.

The extent to which methane gas emission will be a problem in the future, 

especially in the underground mining of subbituminous coals and lignites, has 

not yet been determined. However, the data presented in this report should 

assist in planning new mine development in the vicinity of operating mines 

for which methane emission rates are known and in planning effective methane 

control procedures.

DESCRIPTION OF U.S. COALBEDS 

Geographical Distribution 

Geographically, coal is found in the conterminous United States bordering 

the Atlantic and Pacific Oceans, the Gulf of Mexico, Mexico, and the Dominion 

of Canada; it is found in the mountain provinces, the Coastal Plains, and the 

northern Great Plains. Although coal mining is commonly known to be a major 

industry only in Appalachia and the coal basins of Illinois-Indiana, coal is 

now being mined in 24 of the 34 conterminous States which have significant 

coal resources. 

According to AverittYG coal-bearing rocks underlie about 14 percent of 

the land area of the 48 conterminous States. Figure 1, familiar to most 

persons concerned with coal resources, shows the geographic distribution 

of U.S. coalfields. However, it is more useful to examine this map in 

conjunction with figure 2, also from AverittY7 which shows the distribution 

of the remaining coal resources in the various States. 

Coal Resources and Methane Emission 

All coalbeds contain methane. This gas is formed from plant materials 

by biochemical and bacterial transformations during the peat stage of coal 

deposition and subsequently by metamorphic processes as buried peat increases 

in rank to become coal. Because of the fine pore structure of coal and 

degraded peat, the sorptive capacity of such substances is very large so 

that much of the methane evolved during coalification is held in the peat and 

in the coal. The actual amount of methane retained in the coal depends also

DATA SOURCES 

Most of the data included in this report were obtained from Federal" 

inspection reports for 1971, interviews with mine officials, interviews with 

Federal mine inspectors, back files of coal companies, and charts from 

recording methanometers installed by the Federal Bureau of Mines at a few 

selected mines. Information also was collected from published and unpublished 

reports of the Bureau of Mines and from other pertinent publications. 

PRESENTATION OF DATA 

The summaries and correlations of data obtained in this study are presented in tabular, graphic, and equation form. The most complete set of data 

is given in appendix 1, which contains a list of 66 bituminous coal mines that 

produce at least 1 million cubic feet of methane per day. Included in this 

compilation are the identification and thickness of the coalbed, methane 

emission and coal production rates, ventilation rate, number of drifts, 

shafts, and slopes used for ventilation purposes, shaft depth, and age of 

mine. In addition, because it has been used as a measure of gassiness, the 

ratio of methane emission to coal production rate is included here (col. 5); 

note, however, that this ratio is invariably higher than the actual gas 

content of a ton of coal in place, for methane enters the ventilating air 

from the adjacent strata and the unmined coal as well as from that which is 

mined. Methane continues to be emitted indefinitely after all mining ceases. 

For example, figure 5 shows the effect of a strike-induced idle period on a 

mine in Pennsylvania during 1971. The methane emission rate dropped from a 

high of 1 million cubic feet per day before the strike to a low of 0.7 million 

cubic feet per day during the strike. Following this idle period, the methane 

emission rate rose steadilyandreachedits prestrikevaluewithinabout4 weeks.

Methane emission rate data are useful in planning a new mine in the 

vicinity of an operating mine for which such rates are known. For example, 

figure 6 shows coal contours, surface elevations, and the locations of a 

number of active mines in the Pittsburgh coalbed. These mines are identified 

in the appendixes, which also contain the current methane emission figures 

for each mine. Note in particular the increase in methane emission rate as 

one goes southwest away from the Monongahela River towards deeper cover; this 

factor is considered in detail in the next section. 
A list of 199 mines that emit 0.1 to 12.2 million cubic feet of methane 

per day is given in appendix 2 in order of decreasing emission rate. As noted 

in this appendix, these mines liberate a total of 227 million cubic feet of 

methane per day. 

Appendix 3 presents data on the counties with a methane emission rate in 

excess of 100,000 cubic feet per day. Appendix 4 is a similar compilation by 

coalbed; included here are beds with methane emission rates in excess of 

1 million cubic feet per day. 

RESULTS AND DISCUSSION 

An analysis of the data in appendix 1 indicates the methane emission rate 

depends primarily on the depth of the mine and the coal production rate. This 

is illustrated by the charts given in figures 7 and 8, which show the positive 

trends between these variables for mines in the Illinois Nos. 5 and 6 coalbeds ;

~artonl~ noted the existence of a similar trend between depth and the amount 

of methane released per ton of coal mined in southern Illinois. On the other 

hand, there appears to be very little correlation between methane emission and 

the age (or size) of the mine (fig. 9). Combining these observations, we find 

an excellent correlation between (1) the methane emission rate (MER) in 

12page 223 of work cited in footnote 5.

the mines in the Pittsburgh (Pgh), Pocahontas Nos. 3 and 4 (Poc), and the 

Illinois Nos. 5 and 6 (Ill) coalbeds (figs. 10-12). The equations for 

determining methane emission rate are as follows, in millions of cubic 

feet per day:

MER (Ill) = -0.071 + 0.268 X CPR X D; 10 2 CPR X D 2 0.265 (3) 

The correlation coefficients are 0.91, 0.92, and 0.94 for the Pittsburgh, 

Pocahontas, and Illinois coalbeds, respectively, so that the product of coal 

production rate and depth accounts for over 80 percent of the variability 

in the methane emission rates for each of these coalbeds. Obviously, the 

methane emission rate also is affected by the presence of gobs, faults, 

nearby mining operations, clay veins, and oil and gas wells. 

Note that the equations can be used to predict not only methane emission 

rates but also the ratios of such rates for the three coalbeds at a given 

depth. Thus, with a production rate of 5,000 tons per day and a depth of 

1,000 feet, the ratio of the methane emission rates for the Pittsburgh and 

Pocahontas beds is 2.14, for the Pocahontas and Illinois beds 2.84, and for 

the Pittsburgh and Illinois beds 6.06; this means that the emission rate of 

the Pittsburgh bed is greater than that of the Pocahontas beds which, in turn, 

have an emission rate greater than the Illinois coalbeds. These ratios may 

seem out of line in view of the fact that the quantity of methane adsorbed by 

coal at any given pressure (or depth) is greatest for the Illinois coalbed. 
However, we can only conclude that at least for the Pittsburgh coalbed, 

methane emission rates are dependent on the permeability of the coalbed itself 

and on the gas content and permeability of the adjacent strata. 

Of the total methane emitted by the bituminous coal mines in the conterminous United States, approximately two-thirds (65.8 percent) is emitted by the 

mines in the Pittsburgh (44.5 percent), Pocahontas No. 3 (14.7 percent), and 

the Illinois Nos. 5 and 6 (6.6 percent) coalbeds. The remainder (34.2 percent) 

is emitted by the mines in the other coalbeds. Interestingly, over threefourths (78.9 percent) of the methane emitted by the mines in the conterminous 

United States is emitted by those with emission rates of 1 million cubic feet 

or more per day; 28 mines in this group emit 92.8 percent of all the methane 

from the Pittsburgh coalbed (appendix 1). 

The 199 mines listed in appendix 2 emit 227.0 million cubic feet of 

methane per day. An analysis of data from 231 mines with measurable methane 

liberation rates (but less than 100,000 cubic feet per day) indicates that 

these emit only 4.7 million cubic feet of methane per day. Of the mines in 

the former category, those in West Virginia liberate 46.6 percent, those in 

Pennsylvania, 19.2 percent, those in Illinois, 6.7 percent, and those in 

Alabama, 5.1 percent of the total (appendix 3). Further, the mines in 

Monongalia County, W. Va., emit the largest total volume of methane recorded 

for any county--39 million cubic feet per day; mines in Marion County, W. Va., 

emit 30.4, and those in McDowell County, W. Va., emit 13.1 million cubic feet 

of methane per day. In Pennsylvania, the mines in Washington County emit 11.9 

andthosein Greene County, 11.4 million cubic feet of methane per day. In 

Virginia the mines in Buchanan County emit 21.6 million cubic feet, while 

those in Jefferson County, Ala., emit 10.3 and those in Franklin County, Ill., 

emit 6.6 million cubic feet of methane per day (appendix 4). 

CONCLUSIONS 

Methane emission rate data can be readily compiled from available reports. 

In turn, these data can be correlated with the coal production rate and depth 

for any particular coalbed. A linear correlation holds for the Pittsburgh, 

Pocahontas Nos. 3 and 4, and Illinois Nos. 5 and 6 coalbeds. The correlations 

obtained to date can be used to predict the methane emission rate and subsequently assist in planning effective methane control procedures in bituminous 

coal mines.
