METHANE EMISSIONS FROM U.S. COAL MINES IN 1980 

By Roy H. Grau 111 ' and John C. ~a~cola~ 

ABSTRACT 

This Bureau of Mines report contains a tabulation of methane emissions 

during 1980 for all coal mines located in the United States with emissions greater than 0.1 MMcfd. Listed for each mine are methane emission 

quantity, location, and coalbed. The report also compares records of 

1975 and 1980 and describes relationships between emissions in 1980 and 

the Bureau's coalbed gas content data on 11 mines. 

INTRODUCTION 

Methane gas is a threat to safety in underground coal mines. Research 

by Government and industry has led to great gains in reducing methane 

gas ignitions and explosions. The development of advanced methane control techniques is necessary for the safe operation of more gassy mines 

and the implementation of rapid mining techniques. 

As part of this research, the Bureau of Mines has surveyed total methane emission data from underground bituminous coal mines in the United 

States and tabulated emissions from mines producing over 0.1 MMcfd of 

methane. This report is an update of similar studies previously described in Information Circulars 8733, 8659, and 8558 (2-4).3 -- 

The data from 1980 were compiled from Mine Safety and Health Administration (MSHA) records of air quality-quantity inspections made 

quarterly at each mine. The inspections involve measuring airflow and 

collecting air samples in the main returns. From these data, an average 

methane emission is calculated and used to represent the daily mine 

emission for each quarter. The methane emissions given in this report 

are the averages of the four 1980 quarters and do not include mine emissions from other sources such as degasification projects. Since a previous Bureau study showed that emissions from mines emitting less than 

0.1 MMcfd represented only 2 pct of all emissions, 0.1 MMcfd was chosen 

as a lower limit for data collection (4). -

DISCUSSION OF RESULTS 

METHANE EMISSION STATISTICS 

During 1980, 200 underground coal mines 

in the United States had methane emissions of at least 0.1 MMcfd. These mines 

are listed in order of highest emissions 

to lowest in table A-1 in the appendix 

and alphabetically by coalbed in table 

A-2. Both tables contain each mine's respective coalbed, State, and county. The 

emissions from all mines totaled 

256.3 MMcfd, and the mines were distributed through 11 States and 64 counties. 

A comparison of the emission data for 

1975 (2) and 1980 is shown in table 1. 

Total -emissions increased from 216.3 

MMcfd in 1975 to 256.3 MMcfd in 1980. 

The number of mines emitting 0.5 MMcfd or 

less decreased by 9.0 pct, but the gas 

emitted from this group remained at 8.0 

pct. Also, there was an increase in the 

number of mines producing between 0.5 and 

1.0 MMcfd, as well as those producing 

over 1.0 MMcfd. However, in both categories, the percentage of emissions they 

contributed to the total amount in 1975 

and 1980 was almost equal. The overall 

increase in methane emissions from 1975 

to 1980 may have been caused by a variety 

of factors such as new mines in gassier 

seams, an increase in the size of the 

mines, and the fact that 1980 coal production for underground bituminous coal 

mines in the United States was 337 million short tons compared with 293 million 

short tons in 1975. 

Table 2 gives a comparison of the 10 

mines with the highest emissions in 1975 

and 1980. The emissions from the 10 

highest producing mines increased from 

66.8 MMcfd in 1975 to 82.8 MMcfd in 1980. 

Although the mines that are listed as top 

gas producers in 1975 were all active 

operations in 1980, six were replaced in 

the 1980 list by different mines, all of 

which were located in Alabama or Virginia. Interestingly, these six mines 

ranged from 4 to 14 yr old while five of 

the six mines that were replaced were at 

least 30 yr old. Although this seems to 

indicate that a direct relationship exists between emissions and age, a more 

in-depth observation shows that there is 

no singular relationship between the two 

(A). For instance, in 1980 the following 

mines had these respective ages and 

emissions : 

Blue Creek No. 4...... 6 yr 16.5 MMcfd 

Blue Creek No. 5...... 5 yr 6.2 MMcfd 

Loveridge No. 22.. .... 29 yr 8.2 MMcfd

Previous Bureau studies have reported 

conflicting data on how emissions are affected by coal mine production (4-6, -- - 8). 

Data from this report show that no singu11 

NAP 

lar relationship exists between emissions 

and production. This can be confirmed by 

reviewing the three highest emitting 

mines in 1980 with their respective emissions and coal production: 

Blue Creek No. 4. 16.5 MMcfd 752 Mtpy 

Blue Creek No. 3. 11.1 MMcfd 1,015 Mtpy 

Loveridge No. 22. 8.2 MMcfd 2,142 Mtpy 

5.3 

82.8 

If age and production do affect emissions, it is in combination with other 

factors such as coalbed gas content, geology, permeability, rib length, etc., 

all of which would combine to alter the 

emission rate. 

Figure 1 compares total emissions, 

number of mines, and mean and median 

emissions of all mines for 11 states. 

2,264 

12,344 

Analogous to the large portion of emissions produced by a small percentage of 

mines, a large percentage of emissions 

occur in a few select States and counties. Although mines were located in 11 

States, West Virginia, Alabama, Pennsylvania, and Virginia together had emissions that totaled 215.3 MMcfd or 84 pct 

of total emissions. Additionally, these 

4 States contain 11 counties with the 

highest emission rates of all counties, 

greater than 7.2 MMcfd each. Although 

these counties represent only 17 pct of 

the 64 counties listed, they contain 

mines that produce 72 pct of all emissions. Figure 1 also shows that depending upon location, total emissions can be 

largely dependent upon either the number 

of mines or the average emission per 

mine. Noteworthy is Alabama, which has 

only 14 listed mines yet produces the 

second highest total emissions and has 

the highest mean and median emission per 

mine for any State.

During 1980, 17 of the total 48 coalbeds had total emissions greater than 1.0 

MMcfd. Total emissions, number of mines, 

and mean and median emissions per mine 

for the 10 largest methane producing 

coalbeds are shown in figure 2. The 

Pittsburgh, Mary Lee, and Pocahontas No. 

3 Coalbeds accounted for 67 pct of all 

emissions. The Pittsburgh Coalbed has 

the most mines and highest total emission, but the Mary Lee Coalbed is second 

in emissions and is the highest in gas 

emissions per mine.

EMISSION TREND ANALYSIS 

Since the early 19701s, Bureau research 

has focused on creating a methodology for 

predicting methane emissions. Irani (4) 

showed a relationship between methan'e 

emissions and the product of depth and 

coal production for four major coalbeds. 

During the same time period, the Bureau 

developed a direct method of determining the methane content of coal samples 
obtained from vertical exploration cores 

(9). Diamond (1) gives a complete description of the-direct method, including 

583 test results from 125 coalbeds in 15 

States. The final product of this methodology is gas content per unit weight of 

coal, which can be used as an indicator 

of the coalbedgas content. Although 

Kissell (9) has shown a relationship between measured gas content and methane 

emissions, additional data on gas content, presented in this report, provide a 

new insight into the relationships between total gas content, depth, and methane emission. 

Total gas content is not the only factor affecting the rate at which methane 

will enter a mine airway. Parameters 

such as production, mining methods, methane drainage, mine size, geologic conditions, permeability, porosity, and water 

saturation are also important aspects 

affecting methane emissions. Although 

these factors could not be evaluated for 

this report, the general relationships 

between total mine emissions, total gas 

content, and depth for 1980 data can be

mines were located in seven different 

coalbeds with coal core depths from 427

CONCLUSION AND SUMMARY 

In 1980, there were 200 bituminous coal 

mines within the United States emitting 

at least 0.1 MMcfd, with total emissions 

equaling 256.3 MMcfd. Methane emissions 

increased by 40.0 MMcfd since the last 

Bureau survey in 1975. Seventy mines had 

emissions of 1.0 MMcfd or more, which 

accounted for 80 pct of the total daily 

emissions. The mines listed in this report are located in 48 coalbeds, 17 of 

which have total emissions greater than 

1.0 MMcfd. The Pittsburgh, Mary Lee, and 

Pocahontas No. 3 Coalbeds accounted for 

67 pct of all methane emitted. Although 

the mines were located in 11 States, West 

Virginia, Alabama, Pennsylvania, and Virginia accounted for 84 pct of the total 

emissions. 

Coal core gas content data were available for 11 mines. Relationships were established between gas content and depth, 

emissions and gas content, and emissions 

and depth.
