MiningtheCoal.Coal minersuse giant machines to removecoalfrom the ground. They use two methods: surface or undergroundmining. Many U.S.coalbeds are very near the ground’s surface, and about two-thirds ofcoal productioncomes from surfacemines. Modernminingmethods allow us to easily reach most of ourcoalreserves.

More DetailsMany 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.
