coal mining process

The overallcoal mining processconsists of several sequential stages: (1) exploration of a potentially economiccoalseam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; (2) analysis and selection of amining plan; (3) securing the markets; (4) developing the mine; (5) extracting thecoal; (6)processingthecoalif necessary; and (7) …

Processing coalAfter removing thecoalfrom the ground, the miners may send it to a preparation plant near theminingsite. The plant cleans andprocesses coalto remove rocks, dirt, ash, sulfur, and other unwanted materials. Thisprocessincreases the heating value of thecoal.

Coal MiningandProcessingMethods T his appendix presents additional details on the individualprocessesthat are involved in extraction ofcoalfrom surface and undergroundmines, and the subsequent beneficiation of thecoalincoal processingplants to produce a final product.

Coal miningis only a temporary use of land, so it is vital that rehabilitation of land takes place onceminingoperations have stopped. In best practice a detailed rehabilitation or reclamationplanis designed and approved for eachcoal mine, covering the period from the start of operations until well aftermining…

Mining coal.Coalminers use large machines to removecoalfrom the earth. Many U.S.coaldeposits, calledcoalbeds or seams, are near the earth's surface, while others are deep underground.Modernminingmethods allowcoalminers to easily reach most of the nation'scoalreserves and to produce about three times morecoalin one hour than in 1978.

Many breakers and washeries efficiently handle the coarser sizes, but waste thecoalfines. This problem is assuming major importance due to the increase in the amount ofcoalfines being produced by the mechanization ofcoal mining. Flotation offers a very satisfactory low-cost method for recovering a fine, low ash, cleancoalproduct at a profit.

The former is known as undergroundmining, the latter as stripminingor mountaintop removal. Eitherprocesscontributes a high level of damage to the environment: #12 Noise pollution. One of the most obvious (albeit perhaps least harmful)environmental effects of coal miningis noise pollution.
