The rooms can be mined out using conventional charge-and-blast techniques or, more commonly now, with a machine called a continuous miner. The continuous miner drills into the rock until it forms an excavated room, perhaps 20 to 30 feet (6 to 9 meters), leaving in place a rock pillar to support the "roof" [source: United Mine Workers of America ].
A pulley is one of the physic's six non-motorized simple machines—in this case, one that reduces either the effort necessary to lift a load or the direction in which the force needs to be applied in order to move the load—or it may do both things: reduce the .
