Abstract
The invention relates to an intelligent air-water spraying control dust falling device for the blasting of coal mine. The device comprises a valve bank control system, a spraying air-water mixing cavity and nozzles. The bottom of the valve bank control system is connected with a pressure water source and a pressure air source through a pipeline respectively. A shock wave receiving plate close to the top is arranged on the right end face of the valve bank control system. A mechanically-controlled pneumatic valve connected with the valve bank control system is arranged below the shock wave receiving plate. The top of the valve bank control system is connected with the spraying air-water mixing cavity through a water duct and an air delivery pipe. A plurality of nozzles are arranged to form a sector on the right end face of the spraying air-water mixing cavity. According to the dust falling device, the dust concentration, particularly the concentration of respirable dust, of a blasting working surface can be effectively reduced, and a high-concentration gas generated in a heading process can be blown away by pressure air to be prevented from being accumulated on a heading end; and flame generated by the blasting is eliminated, so that the dust falling device can be conveniently used for various sites of the coal mine, and has a multifunctional effect.
