GEOLOGIC INVESTIGATIONS OF UNDERGROUND COAL MINING PROBLEMS by C. M. McCul loch, 1 P. W. Jeran, 1 and C. D. Sul l ivan2 ABSTRACT A series of geological surveys were completed in six coal mines in connection with a Bureau of Mines research program on methane by: 6. This report explains the advantages of geologic maps and fence diagrams in coal mining and how the knowledge gained from such geologic investigations of mines can help control many underground problems. Additional Physical Format: McCulloch, C.M. (Charles M.). Geologic investigations of underground coal mining problems ii, 30 p. (OCoLC) Material Type. This paper covers geologic exploratory methods, data organization, and the value of collecting and interpreting geologic information in coal mines to enhance safety and production. The implementation of the methods described above has been proven effective in predicting and mitigating adverse geologic conditions in underground coal : Mark Van Dyke, Ted Klemetti, Joe Wickline.

Underground coal mining is the extraction of coal from below the surface of the earth. The coal is worked through tunnels, passages, and openings that are connected to the surface for the purpose of the removal of the coal. Mechanical equipment breaks the coal to . @article{osti_, title = {Geologic factors affecting coal mine roof stability in the eastern United States}, author = {Kane, W F and Milici, R C and Gathright, II, T M}, abstractNote = {Roof falls in underground coal mines are a continuing source of trouble for mine operators. Fatalities and injuries are a prominent concern, but lost time due to cleanup and disruption of mining. "Major problems facing the development of coal and gas resources of the Hartshorne Coalbeds include the complex distribution of minable and unminable coal, high methane content and bed pressure, faulting, variations in degree of dip, presence of natural gas fields in associated sandstones, and legal problems, caused by local geologic characteristics, in identifying gas Cited by: 3. @article{osti_, title = {Geology in coal resource utilization}, author = {Peters, D.C.}, abstractNote = {The 37 papers in this book were compiled with an overriding theme in mind: to provide the coal industry with a comprehensive source of information on how geology and geologic concepts can be applied to the many facets of coal resource location, extraction, and .

The U.S. coal industry serves a vital role in the nation’s economy by producing fuel for more than half of its electricity. Despite the industry’s importance, industry financial data for —the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2.

Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step by-step mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a side) left to support the mine Size: KB. Miners face numerous problems in the process of underground coal extraction such as high temperature, humidity, coal and silica dusts, harmful gases, the rock stresses, and the disturbance due to.
