What is the process of coal mining? - R4 DN

2021-3-9 · What is the process of coal mining? The surface rock (called overburden) covering the coal is then blasted with explosives and removed by excavators. Some coal is mined by the Bord and Pillar method. This is where a machine continually cuts into the coal. It tunnels through the coal seams leaving pillars supported by roof bolts to hold up the roof.

Coal Production - an overview | ScienceDirect Topics

Coal production continues to grow globally due to the demand for low cost energy and iron and steel, as well as cement. Coal, based on the current extraction rates, will last about 115 years longer than conventional oil and gas reserves, with an estimated 1.1 trillion tonnes of proven coal reserves worldwide. Ten countries are responsible for 90% of the total global coal production.
