What is the process of coal mining? - R4 DN

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.
