These tunnels result from the excavation of a series of "rooms" into the coalbed, leaving "pillars" or columns of coal to help support the mine roof. In conventional room-and-pillar mining, the coal is broken up by explosives, loaded onto a vehicle by a mechanized loading machine, and transported from the production area by shuttle cars.
