Rotor sprinklers are different than traditional underground spray head sprinkler systems in several ways. One of the key parts of a sprinkler system is the sprinkler heads, and rotor heads are completely distinct. Rotor sprinkler heads are larger than typical spray heads, and they can cover more land than the average underground system.
transported to the underground ore bins or direc tly to the main haulage level. Finally, ore is collected on the main haulage level and transferred to an underground crusher for size reduction to facilitate transportation by conveyors or skips through shafts (see Underground Mining Transportation Systems).
