PreMining Inv entory land A coal company’s first step in compiling a surface mining permit application is to gather data in a premining inventory from the site, including facts regarding: • surface and gr oundwate r quality and quantity • alternative water supplies • soil depth, type, and quality • The first step used in estimating methane emissions from surface mining and postmining activities is to segregate the surface mines geographically by coal basin and by state The Energy Information Agency’s (EIA) Coal Industry Annual reports state and countyspecific underground and surface coal production by yearUS Surface Mines Emissions Assessment Surface mining techniques include strip mining, mountaintop removal mining, and openpit mining Although mining and reclamation operations are complex and regionally specific, the overall coal mining process consists of similar sequential stages (preparing the surface, drilling, blasting, overburden removal, loading the deposit, haulage of the mined deposit, and rehabilitation)Effects of surface coal mining and land reclamation on
The first step in surface coal mining is: to remove and
The first step in surface coal mining is: to remove and set aside the soil that covers the area to be mined to use heavy equipment to take core samples to test and see if quarrying would be more effective to make cuts in the coal for easier removal The first step in selecting the most Highwall mining is a coal mining method for recovery of outcropped coal by mechanical excavation without removal of overburden A continuous miner with single or multiple Surface mining is generally considered to provide better recovery, grade control, flexibility, safety, and working environmen ts Surface Mining Methods and Equipment EOLSS Surface Mining Strip mining and mountaintop removal are two popular surface mining strategies when coal seams are located close to the surface of the earth Strip Mining In strip mining, the first step is to strip off the vegetation and soil in the vicinity of the surface to be mined for coalCoal Mining: How Is Coal Mined?

Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining In surface mining, workers simply remove any overlying sediment, vegetation, and rock, called overburden Economically, surface mining is a cheaper option for extracting coal than underground mining The first step in selecting the most Highwall mining is a coal mining method for recovery of outcropped coal by mechanical excavation without removal of overburden A continuous miner with single or multiple Surface mining is generally considered to provide better recovery, grade control, flexibility, safety, and working environmen ts Surface Mining Methods and Equipment EOLSS Surface Mining Strip mining and mountaintop removal are two popular surface mining strategies when coal seams are located close to the surface of the earth Strip Mining In strip mining, the first step is to strip off the vegetation and soil in the vicinity of the surface to be mined for coalCoal Mining: How Is Coal Mined?

Wirtgen Surface Mining: Maximizing coal recovery by minimizing fines Wirtgen Group mining coal with a Wirtgen surface miner is a first step toward substantial savings in the process chain Relatively shallow coal deposits are generally extracted by surface mining, and deeper deposits are extracted by underground mining (more detailed descriptions of surface and underground mining processes can be found in Appendix E) There are also situations in which a seam is mined by surface methods first, and then if adequate reserves are 4 Coal Mining and Processing Coal: Research and Mining Mining Surface mining: It has been estimated that more than twothirds of the world’s yearly mineral production is extracted by surface mining There are several types of surface mining, but the three most common are openpit mining, strip mining, and quarrying These differ from one another in the mine geometries created, the techniques used, and the minerals producedMining Surface mining Britannica
