Coal Mining. Print. 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.

Dec 23, 2020 6:15am. One coal mine can feed up to four coal processors. It is a good idea to have two storages in parallel for the processed coal. One storage to feed one or more power plants, cement factory etc. and the other for exporting the coal. It is recommended to have more than one power plant.

Processing of Coal. Once mined, coal may go to a preparation plant located near the mining site where it is cleaned and processed to remove impurities such as rocks and dirt, ash, sulfur, and other unwanted materials. This process increases the amount of energy that can be obtained from a unit of coal, known as its heating value.
