Impact of greenhouse gases on surface coal mining in

2018-8-20  Coal ore extraction involves both surface (open-pit) and underground mining techniques. The method selected depends on a variety of factors, including the nature and location of the deposit, size, depth, and grade of the deposit (Norgate and Haque, 2010).Surface mining operates in two distinct stages, overburden removal and coal extraction, as well as the recovery of the mined area.

Background review Subsidence from coal mining activities

Background review: subsidence from coal mining activities Major underground coal mining in Australia mainly occurs in the coal basins of New South Wales and Queensland. Longwall is currently the most common method of underground coal mining in Australia, as it is safer and more efficient in extracting coal than other extraction techniques.

In surface coal mining it is common practice to store coal in large piles. The piles, usually worked by bulldozers, are subject to wind erosion causing emission

Carbon Dioxide Emission Factors for Coal

2020-1-14  Carbon Dioxide Emission Factors by Coal Rank and State of Origin. The (arithmetic) average emission factors obtained from the individual samples (assuming complete combustion) (Table FE4) (10) confirm the long-recognized finding that anthracite emits the largest amount of carbon dioxide per million Btu, followed by lignite, subbituminous coal, and bituminous coal.

Other research on the environmental impact over the life cycle of bituminous coal is linked to surface mining (a cradle to gate analysis). Five opencast mines in the USA were analysed in the work of Ofentse Ditsele and Kwame Awuah-O ei [16].

Bottom-Up Estimates of Coal Mine Methane

2020-2-28  China has large but uncertain coal mine methane (CMM) emissions. Inverse modeling (top-down) analyses of atmospheric methane observations can help improve the emission estimates but require reliable emission patterns as prior information. To serve this urgent need, we developed a high-resolution (0.25° × 0.25°) methane emission inventory for China’s coal mining using a recent publicly

Main factors influencing the wide range of apertures (from 50 to 400 mm) of mining-induced horizontal fractures (Torezko-Snezhnyanskaya coal area, Ukraine) at traditional (without grout injection into bed separation) longwall coal mining were analysed. Apertures of these fractures were directly measured (using an original experimental device) in vertical boreholes drilled from ground surface

SURFACE MINING METHODS A surface mine is an open-air excavation for removing minerals. Surface mining can be employed to extract metallic or nonmetallic mineral from any near-surface deposit in any rock type. Near-surface generally implies deposit less than 500 ft. the size of the deposit may range from a few tons to more than 100 million tons.
