Coal seam drill-miner

A coal seam drill-miner is characterized by comprising a drill pipe, a collector, and a coal-water separating mechanism. The drill pipe penetrates in a hole protecting pipe and the collector. The hole protecting pipe and the front end of the collector are connected in a sealing mode. A gas pumping outlet and an atomizer are sequentially arranged at the top of the collector from front to back, and a coal-water delivery port is formed in the bottom of the collector. The coal-water separating mechanism which is arranged upwards in an oblique mode comprises an airtight shell and a spiral conveyor device disposed in the shell. The spiral conveyor device is coaxially sleeved with a dewatering filter net cover. A feed inlet and a water outlet are formed in the bottom of the coal-water separating mechanism, and a discharge outlet is formed in the top of the coal-water separating mechanism. According to the coal seam drill-miner, preliminary separation of coal from gas is effectively conducted through the collector, and separation of coal from water is effectively conducted through the coal-water separating mechanism.
