Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Coal mining - Simple English Wikipedia, the free encyclopedia

Coal mining is the process of getting coal out of the ground. It is part of the mining industry.Coal is used as a resource for making electricity.. Extraction. Surface mining is done when the coal is near the surface. Coal miners remove the soil above the coal. The coal can then be removed without the coal miners having to go deep underground..

Optimisation of cutting cycles in conventional underground

Conventional coal mining Conventional underground coal mining relies upon the use of continuous miners in order to extract coal reserves from underground coal seams. [2] In combination with the continuous miners, shuttle cars are used to transport the extracted coal from the face to a transfer point (feeder breaker).

Coal preparation plant - Wikipedia

Coal needs to be stored at various stages of the preparation process, and conveyed around the CPP facilities. Coal handling is part of the larger field of bulk material handling, and is a complex and vital part of the CPP.. Stockpiles provide surge capacity to various parts of the CPP.
