ABSTRACT 

This Bureau of Mines report tabulates methane emissions from U.S. bituminous coal mines with daily emission rates of at least 100,000 cfd according to 

States, counties, and coalbeds. Most of the methane emitted is from mines in 

the Appalachian States. Total dailyemissionin 1975 was 216.3 MMcfd, compared 

with 227.0 MMcfd in 1971 and 214.5 MMcfd in 1973. 

Thirty counties in nine States had daily methane emissions of 1 MMcfd or 

more, These emitted 93 percent of the total methane. The highest emissions 

were from Monongalia County, W. Va,, which accounted for 18.9 percent of the 

total. This was followed by Marion County, W. Va., 9.6 percent; Buchanan 

County, Va., 8.5 percent; Jefferson County, Ala., 6.1 percent; and Washington 

County, Pa., 5.9 percent. The Pittsburgh coalbed emitted 45.7 percent of the 

total methane, followed by the Pocahontas No. 3 coalbed with 12.9 percent. 

The report lists 196 mines, of which 60 had daily methane emissions of 

1 MMcfd or more. Included in this compilation are the identification and 

thickness of the coalbed, methane emission, coal production and ventilation 

rates, number of drifts, shafts, and slopes used for ventilation purposes, 

shaft depth, age of mine, and gas-to-coal ratio. 

INTRODUCTION 

Methane in coal mines constitutes an explosion hazard with which the 

Bureau of Mines has been concerned since its establishment in 1910. In recent 

years, the Bureau has been conducting a vigorous and increasingly comprehensive methane control research program. The need for this program was evidenced by the fact that while coal mine fatalities were decreasing in the 

years from 1965 to 1970, the number of fatalities due to ignitions and

Pa. 
explosions in the underground coal mines was increasing (12) .4 This has been 

attributed largely to the fact that deeper coalbeds were being mined at faster 

rates and that more methane was emitted under these conditions. 

All parts of our country's coalfields are not equally gaseous. This has 

been pointed out in previous reports (4-51, - - updated herein, which tabulate 

daily methane emissions according to mines, States, counties, and coalbeds for 

underground bituminous coal mines in the United States. The Pittsburgh coalbed emitted 45 to 47 percent of the total methane emissions in 1971 and 1973. 

The Pocahontas No. 3 coalbed emitted 16 percent of the total for both years, 

and the Illinois Nos. 5 and 6 coalbeds emitted 7 percent of the total for both 

years. In 1971 and 1973, West Virginia produced more methane than any other 

State containing mines with methane emissions of at least 100,000 cfd. For 

both years, New Mexico was the least gassy State of those containing mines 

with methane emissions of at least 100,000 cfd. 

The resent fuel shortage has led to some interest in the recovery of 

methane from coal. The data in the three Bureau reports can be used to 

direct investigation to those areas with demonstrated high methane emissions. 

Cross reference to geographical needs for further gas may pinpoint the most 

economically attractive areas for further consideration. 

Comparison of the data from several years may show trends in methane 

emissions for individual mines, coalbeds, counties, or States. Notable 

changes in these emissions can initiate research to determine causes of variations. The results of such research will aid in the understanding of methane 

emission and its controlling factors. This understanding will help in developing mining technology to improve the safety of the mine environment. 

ACKNOWLEDGMENTS 

The authors express their appreciation to the district and subdistrict 

managers, supervisors, and inspectors of the Mining Enforcement and Safety 

Administration (MESA) who willingly contributed their time and experience. 

The successful completion of this study would not have been possible without 

their cooperation. 

DATA SOURCES 

The data presented in this report were obtained from the MESA district 

and subdistrict offices. They were supplemented by interviews with officials 

and mining companies with whom the Bureau has active cooperative agreements 

and with individual mine inspectors. The Bureau has 29 continuous -recording 

methanometers installed at the exhaust fans of 14 mines; data from these fans 

are being treated separately for a report in a different form because they are 

much more detailed. 

4Underlined numbers in parentheses refer to items in the list of references 

preceding the appendixes. 
METHANE EMISSIONS INTO MINE WORKINGS 

Hydrocarbon gases are an integral part of coal formed by biochemical and 

physical processes which take place during conversionof accumulated plant 

material into coal. Methane constitutes 98 percent of the hydrocarbon gases 

formed during genesis of coal (8). - Most of the remaining 2 percent is made up 

of ethane, propane, butane, and pentane. A large part of these gases are 

retained in the coal. 

When a coalbed is mined, the equilibrium conditions change and the methane and other gases within the coal migrate to the mine opening. This migration is by diffusion through the solid coal and flow through the fractures. 

In U.S. coalbeds, flow through fractures has been reported to be the dominant 

method of migration (1). - 

Recent studies utilizing continuous-recording methane monitors have shown 

that changes in the emission rates from advancing sections in the Pittsburgh 

and Beckley coalbeds are related to length of virgin mine ribs (6-7). - - In some 

coalbeds in this country, methane is also contained in the rock strata adjacent to the coal. One study conducted at a retreating longwall face showed 

methane emissions to average 34 cfm prior to the first fall of roof (9); 

breakup of roof strata behind the longwall face increased the methane-emissions to more than 700 cfm. 

PRESENTATION OF DATA 

The data are summarized in tabular form. The most detailed data, in 

appendix A, provide information on 60 bituminous coal mines that produced at 

least 1MMcfd of methane, the identification and thickness of the coalbed 

being mined, daily methane emission and coal production rates, ventilation 

rates, number of mine openings used for ventilation purposes, average shaft 

depth, and age of mine. The ratio of methane emissions to coal production as 

cubic feet of gas produced per ton mined has been taken as a measure of gassiness in the past and is included in this report for comparison with figures 

from past years. This'quantity is only an approximation, based on average 

daily coal production and methane removed by ventilation, for mature mines. 

Appendix B lists 196 mines in order of daily gas emission rates from 11.6 

to 0.1 MMcfd. These mines emitted a total of 216.3 MMcfd. This list does not 

contain mines which have daily methane emission rates less than 100,000 cfd; 

data for these mines are not available. 

Appendix C presents methane emission data by State and county for mines 

with emission rates in excess of 100,000 cfd. 

Appendix D lists methane emission from mines in coalbeds with emissions 

of at least 1 MMcfd per coalbed. 

A complete listing of methane emissions for States and counties containing mines with total daily methane emission rates of at least 100,000 cfd is

The Pittsburgh coalbed underlies southwestern Pennsylvania, eastern Ohio, 

and northern West Virginia. Mines in this coalbed emitted more methane (98.8 

MMcfd) than mines in any other coalbed and accounted for 45.6 percent of the 

total emission. The next highest emission was from the Pocahontas No. 3 coalbed, 27.8 MMcfd or 12.8 percent of the total. This coalbed underlies southern 

West Virginia and northwestern Virginia. Mines in the Illinois Nos. 5 and 6 

coalbeds emitted 14.0 MMcfd, or 6.4 percent; mines in the Freeport coalbeds, 

12.5 MMcfd, or 5.7 percent; and mines in the Kittanning coalbeds, 11.0 MMcfd, 

or 5.1 percent. Collectively, the foregoing mines accounted for 91 percent of 

the total methane emission (appendix D). It has been reported (11) that the 

Illinois 5 coalbed is correlative with the Kentucky 9 and that the Illinois 6 

coalbed is correlative with the Kentucky 11. These coalbeds are listed separately in this report to be consistent with previous reports (4-5). - - 

Table 1 shows the numerical distribution of coal mines with a methane 

emission rate of at least 100,000 cfd by State and coalbed. West Virginia had 

the greatest number of mines in this category (64), followed by Pennsylvania 

with 43. There are more of these mines (50) in the Pittsburgh coalbed than 

any other coalbed in the United States. 
TABLE 1. - Numerical distribution of coal mines with an emission - rate of at least 100,000 cfd, by State and coalbed 

Total daily methane emissions from U.S. bituminous coal mines are compared for 1971, 1973, and 1975 (table 2). In 1971, the total daily methane 
emissions were 227.0 MMcfd from 199 mines (5); in 1973, the emissions were 214.5 

MMcfd from 192 mines (4); and in 1975, the emissions were 216.3 MMcfd from 196 mines. 

Table 2 lists only those coalbeds which contained mines emitting at least 100,000 

cfd in 1975. These data for 1971, 1973, and 1975 show that the change in emissions 

from coalbeds tends to correlate with the change in the number of mines operating in 

these coalbeds. A notable exception is the Pittsburgh coalbed, which had a decline 

in emissions from 102.8 MMcfd to 98.8 MMcfd between 1971 and 1975 but an increase in 

the number of active mines from 47 to 50. This decline may be related to the 

increased use of gob degasification boreholes by several mines operating in the coalbed. The lack of accurate data on the output of these boreholes precludes a 

conclusion.

A comparison of counties producing 1 MMcfd or more of methane in 1971, 

1973, and 1975 shows that the counties which produced the most gas have

County, W. Va., Marion County, W. Va., and Buchanan County, Va., have 

remained first, second, and third, respectively.

CONCLUSIONS 

In 1975, there were 196 bituminous coal mines in the United States emitting 100,000 cfd of methane or more. This is an increase of four mines since 

1973. The total methane emissions from these mines in 1975 was 216.3 MMcfd, 

an increase of 1.8 MMcfd since 1973. Sixty mines had emissions of 1 MMcfd or 

more and accounted for 79 percent of the total methane emissions. 

In 1975 the Appalachian region led all other coal mining areas in the 

United States in methane emissions. It contained 79 percent of the gassy 

mines and accounted for 86 percent of the total methane emissions. The western coalfields had 6 percent of the mines and 6 percent of the daily methane 

emissions. The centralbasincoalfields had 15 percent of the mines but only 

8 percent of the total methane emissions. This indicates that research into 

methane emissions and their control should be directed primarily towards the 

Appalachian and western coalfields. 

With increased emphasis on coal production to achieve energy independence, 

there will be an increase in methane emissions as more mines are opened in 

deeper coalbeds. This increase can be maintained by the use of degasification 

techniques which remove methane from the mine environment prior to its entering mine ventilation systems (2-3, 10). Methane removed in this way could be -- - utilized as an auxiliary energy source.
