Pneumatic separating system for continuous mining machine
A coal mining system is provided including a pneumatic separator having an air lock to separate the coal dust from the remainder of the coal aggregate in the system. A pneumatic suction means is provided to convey the dislodged coal aggregate from the mine face as it is mined by a mining machine. A duct carries the coal aggregate from the mining machine, past the separator where the coal aggregate remainder is transferred to an auger conveyor with the coal dust proceeding to a pollution control mechanism, such as a cyclone separator at a remote location outside the mine. A jet engine provides the suction for the system. A hopper is provided above the inlet to the auger conveyor providing the blocking concentration of coal to assure maintenance of the full vacuum in the pneumatic duct. A level control switch is operated by pivotal spade in the hopper and a similar switch is provided to sound an alarm when the hopper is filled to capacity. The auger conveyor discharges onto a second belt conveyor open to the ambient conditions to convey the coal aggregate remainder to its final location. The mining machine and the pneumatic separator are mounted on tracks for movement along the mine shaft.
