Coal mining - Wikipedia

Most coal seams are too deep underground for opencast mining and require underground mining, a method that currently accounts for about 60 percent of world coal production. In deep mining, the room and pillar or bord and pillar method progresses along the seam, while pillars and timber are left standing to support the mine roof.

Rockwell Automation drives Underground Mining operations

2014-10-30  The shorn coal tumbles onto a conveyer below the shears, and is conveyed to the “stageloader” where it is crushed and dumped onto the main conveyer belt that eventually hauls it out of the mine. Integral to the long-wall shear and conveyor is a moving metal roof that protects it from the thousand plus feet of ground above.
