After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal
The coal is then loaded on to large trucks or conveyors for transport to either the coal preparation plant or direct to where it will be used Mine rehabilitation Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped
Many breakers and washeries efficiently handle the coarser sizes, but waste the coal fin This problem is assuming major importance due to the increase in the amount of coal fines being produced by the mechanization of coal mining Flotation offers a very satisfactory low-cost method for recovering a fine, low ash, clean coal product at a profit

outside the mining area for placement and storage In the Midwest, where the surface topography and coal seams are generally flat, it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined ()In some situations in the eastern United States, a coal seam occurring near the top of mountains is .
Coal mining is the process of extracting coal from the ground Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine a pit, and the .
Coal is a solid that, if we are to use it, must be extracted from the earth This is coal mining, going into the earth to remove coal for our consumption The basic steps of mining and processing coal are described below There are two general methods of coal mining: surface mining and underground mining Surface Mining
Coal mining - Coal preparation: As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment .
A thorough understanding of subsistence patterns in a particular region allows the effects of underground mining on the surface to be quantified The coal mining industry uses a range of engineering techniques to design the layout and dimensions of its underground mine workings so that surface subsidence can be anticipated and controlled
