How is coal mined and extracted? | Planète Énergies

Jul 7, 2015 . Conveyors or cars (railway wagons) transport the coal to vertical shafts for removal from the mine. After the coal is brought up to the surface by conveyors, it undergoes a process that removes sand and mud by immersing the coal in a solution of water and tiny magnetite particles. The different elements.

Coal Mining and Production

Shallow, flat coal deposits are mined by surface processes, which are generally less costly per ton of coal mined than underground mines of simi- lar capacity. Strip mining is one of the most eco- nomical surface processes. Here removal of overburden and coal extraction proceed in par- allel strips along the face of the coal.
