What is the process of mining coal? - AskingLot

Click to see full answer. In respect to this, what happens after coal is mined? Processing coal After removing the coal from the ground, the miners may send it to a preparation plant near the mining site. The plant cleans and processes coal to remove rocks, dirt, ash, sulfur, and other unwanted materials. This process increases the heating value of the coal.
