Green technique in coal mining (Journal Article) | ETDEWEB

The concept of green technique in coal mining was proposed. Its connotation and technical system were explained. The theory of the green technique in coal mining is the distribution behaviour of joints, fractures and bed separations, and the seepage flow behaviour of methane and water in the broken rock strata caused by the key strata break after mining.

Coking coal of the United States—Modern and historical ...

Coking coal, or metallurgical coal, has been produced in the United States for nearly 200 years. Coking coal is primarily used in the production of coke for use in the steel industry, and for other uses (for example, foundries, blacksmithing, heating buildings, and brewing). Currently, U.S. coking coal is produced in Alabama, Arkansas, Pennsylvania, ia, and West ia.

from coal beds may actually reduce methane emissions to the atmosphere by removing the gas that is otherwise released during coal mining. As part of the President's Climate Change Action Plan, established in 1993, coal-mine oper-ators are being encouraged to recover and use coal-bed methane for energy. Methane Migration In some areas, methane ...

Mined Areas of the Weir-Pittsburg Coal Bed

A coal bed about 3 feet thick has been mined in the McCune area in western Crawford county. This thickness is comparable to the average thickness of the Weir-Pittsburg coal bed ill the mined areas. The coal in these western areas has not been mined extensively, however, because of the higher mining costs at greater depth.

Coal - Wikipedia

Coal bed methane extraction is important to avoid mining accidents. The deadly London smog was caused primarily by the heavy use of coal. Globally coal is estimated to cause 800,000 premature deaths every year, [133] mostly in India [134] and China.

How is Coal Mined - Pediaa.Com

As coal is a fossil fuel that is obtained from beneath the surface of the earth one can wonder how is coal mined. Coal is created when organic matter such as plants and dead bodies of animals gets buried under overlying rocks. This organic matter is transformed into black rocks with passage of time and great pressure from the weight of the rocks from above.

Mining Mapping - Maryland

Coal Mining in Maryland. Through grant money provided by The Office of Surface Mining through the Coal Mine Mapping Initiative, MDE has been able to partner and collaborate with Maryland Environmental Services, Maryland State Archives, and Frostburg State University to provide an online repository of historic underground coal mines to the public.

Coal Bed Methane Drilling - an overview | ScienceDirect Topics

The miner's main concern with coal bed methane (CBM) has been how to get rid of it [1]. Techniques to deal with CBM in mines have ranged from the classic canary in a cage to detect an oxygen-poor atmosphere to huge ventilation fans to force the replacement of a methane-rich environment with outside air, to drilling CBM wells in front of the coal face to try to degas the …

About Coal Mine Methane - US EPA

Underground coal mines account for the vast majority of methane emissions from coal mining in the United States and globally. Most methane from coal mining is released in the form of diluted VAM. Less significant sources of CMM come from surface mines and post-mining activities, such as storage and transportation.

Coal Gas | Coal Mine Methane | Coal Seam Methane

Coal Bed Methane (CBM) or Coal Seam Methane (CSM) is primary coal seam gas collected from unmined coal beds. These coal seams are drilled down into, releasing the associated gas which is extracted and can be used to generate electricity. CBM consists of over 90% methane and can be harvested independently of coal mining in some locations.
