daily emissions have declined from 227 MM ft3 in 1971 to 214.7 MM ft3 in 1973. 

The highest average daily emissions in million cubic feet per day observed in 

U.S. bituminous coal mines were, in decreasing order, Monongalia County, 

W. Va. , 40.7 ; Marion County, W. Va. , 23.1 ; Buchanan County, Va. , 22.1;

INTRODUCTION 

The presence of methane in the air of coal mines constitutes an explosion 

hazard with which the Bureau of Mines has been concerned since its establishment in 1910. Darton reported on the occurrence of explosive gases in 

coal mines, based on a study begun in 1907 under the supervision of J. A. 

Holmes , who subsequently became the first director of the Bureau of Mines. 

His data were obtained from the anthracite fields in Pennsylvania and the 

southern bituminous fields in Illinois. His specific objective was "to obtain 

information on the origin of the inflammable gases in coal and the conditions 

under which they occur ." 

In recent years the Bureau has been conducting a vigorous and increasingly 

comprehensive methane control research program. The need for this program is 

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 explosions in underground coal mines was increasing (2). This is attributed largely 

to the fact that deeper coalbeds were being mined at faster rates and that 

more methane was emitted under these condtions.

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 established. Hmever, the data presented in this report, which 

supplements a previous Bureau survey of methane emissions (4) , 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 . 

AC KN CXJLE DGMENT S 

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. Further, special credit is due G. L. Hassett and E. M. 

Burse, who collected and tabulated information frm Federal mine inspection 

reports ; M. A. Trevits , who checked the tabulated data included here; and 

P. J. Scott, who collected and summarized information from other sources. 

DATA SOURCES 

The data presented in this report were obtained from Federal coal mine 

inspection reports for 1973, interviews with mine officials, and interviews 

with Federal mine inspectors. Although the Bureau has 22 continuous-recording 

rnethanometers installed at the exhaust fans of 14 mines, the data from these 

instruments have not been included because they are not available from all 

mines . 

METHANE IN COALBEDS 

All coalbeds contain methane. It is formed from plant material by 

biochemical and bacterial transformations that occur during the peat stage 

of coal deposition and by subsequent metamorphic processes as buried peat 

increases in rank to become coal. The fine pore structure of coal and 

degraded peat makes their sorptive capacities very large, so that much of 

the methane evolved during coalification is retained in the peat and in the 

coal. Kim (5) has reported that methane constitutes about 98 percent of the 

hydrocarbon gases fonned in the genesis of coalbeds. Concentrations of other 

hydrocarbon gases range from 1 to 20 parts per million. These gases include 

ethylene , propane, propylene , butanes , pentanes , hydrogen, he lium, oxygen, and 

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

the depth of overburden, the hydrostatic head, and the location of faults and 

free surfaces. 

When a coalbed is mined, the equilibrium conditions change and methane 

and other gases migrate from the coalbed into the active mine workings. The 

flow of methane from coal into the mine workings is a two-step process consisting of diffusion and flow through fractures. The importance of diffusion in 

controlling the emission of methane in mines was examined by defining and 

calculating an in situ diffusion parameter for a hypothetical unfractured lump 

of coal in the Pittsburgh and Pocahontas No. 3 coalbeds. The values obtained 
are similar to those obtained with lump coal in laboratory experiments. 

Methane flow and pressure data taken from a mine in the Pocahontas No. 3 

coalbed were compared with flow rates from lump coal obtained in laboratory 

experiments. The results indicated that the main source of gas from the 

Pocahontas No. 3 coalbed was the coalbed itself (6). - 

McCulloch (8) has reported that a geologic study of the Lower Kittanning 

coalbed in central Pennsylvania showed a high methane content in the strata 

overlying the coalbed. In a methane emission study (1) conducted in 1969 on a 

longwall section, the average methane emission rate from the coalbed during 

mining at the face and development of the headings at the tailend of the face 

was 34 ft3/m over 22 consecutive shifts (7-112 days). Subsequent caving of 

the gassy overlying strata increased the emission to rates ranging from 702 

to 1,049 ft3/min. This mine later utilized vertical holes drilled into 

developing gob to drain methane. These boreholes have removed up to 1 MM 

ft3/d of methane and reduced the methane content in the immediate returns 

to less than 1 percent (3). - 

Methane can be removed from a coalbed before it is mined by drilling 

vertical holes into the coalbed with subsequent stimulation by hydrofracturing 

or by horizontal holes drilled into virgin coalbed from large ventilation 

shafts or specially designed boreholes sunk to the coalbed in advance of 

mining. The gas from such holes is of pipeline quality, and cmercially 

significant quantites have been produced. Deul estimates the quantity of 

methane contained in minable coalbeds less than 3,000 feet deep in the conterminous United States at 260 trillion ft3 (2). This is a potential resource, 

and the production of this gas prior to mining will significantly reduce the 

daily emissions from coal mines as well as provide additional energy for the 

Nation. 

PRESENTATION OF THE DATA 

The data obtained in this study have been summarized in tabular form. 

The most complete set of data, given in appendix A, comprises a list of 59 

bituminous coal mines that produced at least 1 MM ft3/d of methane. This 

table also includes the identification and thickness of the coalbed, methane 

emission and coal production rates, ventilation rate, number of mine openings 

used for ventilation purposes, average shaft depth, and age of mine. The 

ratio of methane emission to coal production has been taken as a measure of 

gasiness. 

Appendix B lists 178 mines in order c)i daily gas emission rates from 

12.1 to 0.1 MbI ft3/d. These mines emitted a total of 214,7 PIPI ft3/d. 

Appendix C presents data by counties for mines with methane emission rates 

in excess of 100,000 ft3/d. Appendix D is a similar conpilation by coalbed, 

listing the coalbeds with a daily emission rate of 1 MM ft3 or more. 
DISCUSSION 

In 1973, 276 underground bituminous coal mines in the United States had 

measurable nethane emissions, totaling 216.7 MM ft3 /d. Two million cubic 

feet per day came from 84 mines with emission rates of less than 100,000 

ft3/d. The remaining 192 mines are listed in Appendix B in order of daily 

emission rate. Of these, 59 mines with emission rates of 1 MM ft3/d or more 

(appendix A) emitted 169.0 MM ft3/d, or 78 percent of the total. 

Geographically, the Appalachian area accounted for almost 88 percent of 

the total emissions. West Virginia had the highest emissions (100.7 MM ft3/d), 

followed by Pennsylvania (42.0 MM ft3 /d) , Virginia (27.0 MM ft3 /d) , Alabama 

(11.1 MM ft3/d), Ohio (5.7 MM ft3/d), eastern Tennessee (2.6 MM ft3/d), and 

eastern Kentucky (0.9 MM ft3/d). The only State with significant gas emissions 

outside the Appalachian area was Illinois with 11.8 MM ft3 (5.4 percent of 

total). 

The Pittsburgh coalbed underlies southwestern Pennsylvania, eastern Ohio, 

and northern West Virginia. More gas was emitted from mines in this coalbed 

than any other (99.9 MM ft3/d). The next highest producer was the Pocahontas 

No. 3 coalbed (34.9 MM ft3 /d) which underlies southern West Virginia and 

northwestern Virginia. Following these two were the Illinois Nos. 5 and 6 

coalbeds (11.8 MM f t3 /d) , the Freeport coalbeds (10.9 MM ft3 /d) , and the 

Kittanning coalbeds (10.5 MM ft3/d). All of these accounted for 77.4 percent 

of the methane emissions. 

Comparing data for 1971 and 1973, we find a decline in the number of 

mines with measurable methane emissions from 430 in 1971 to 276 in 1973. The 

greatest reduction was in mines producing less than 100,000 f t3 /d , which 

dropped from 231 to 84. The total of the average daily emissions from this 

group dropped from 4.7 to 2.0 MM ft3/d. Mines producing in excess of 100,000 

ft3/d declined both in number and in total emissions, from 199 mines producing 

227 MM ft3/d in 1971 to 192 mines producing 214.7 MM ft3/d in 1973. 

In recent years several mining companies have begun using vertical boreholes to drain methane from developing gob areas. Methane removed in this 

way does not enter the ventilation air and cannot be measured at the exhaust 

fans. There are at present no systematic data available on the amount of 

methane produced by these boreholes. Based on discussions with mine officials 

and Federal inspectors, this production is estimated to average 15 MM ft3/d. 

This would bring the total methane emission from mines producing in excess 

of 100,000 ft3/d to 229.7 MM ft3/d, or slightly abwe that reported in 1971. 

The present energy situation in the United States makes the daily wasting 

of large quantities of methane seem tragic. However, since this methane is 

contained in ventilating air at usually less than 1 percent concentration, its 

recovery would expend more energy than could be gained. The methane contents 

of gob degasification boreholes and vertical boreholes drilled into virgin 

coal are much higher, almost 100 percent in some cases. Methane removed in 

this way reduces ventilation requirements for mining and becomes a recoverable 

resource. Based on the emission data for 1973, the Appalachian area, with 88 

percent of the total emissions, is the most promising for endeavors of this type.
