The invention discloses a bracket spraying dust reduction emulation simulation device for a coal mine working surface. The device comprises an emulation enclosed test box. The front end of the emulation enclosed test box is provided with an air inlet while the back end is provided with an air outlet; an air flow power supplying device, a dust generating device, a spraying device and a detection system are arranged in the emulation enclosed test box, wherein the air flow power supplying device is used for simulating the air speed and the pressure condition of the coal mine working surface and is arranged at the water inlet; the dust generating device is used for simulating the dust generating state of the coal mine working surface and is arranged on the front part of the emulation enclosedtest box; the spraying device is used for simulating the spraying state of a bracket nozzle on the coal mine working surface; and the spraying device and the detection system are arranged in the middle of the emulation enclosed test box respectively. The emulation enclosed test box is adopted and relevant data of the emulation enclosed test box is acquired and analyzed by using the detection system, so technical support is provided for scientific and reasonable arrangement of a nozzle on the coal mine working surface.
Description
technical field [0001] The invention relates to a simulation device of a coal mine working face, in particular to a simulation device for spraying and dust reduction of a coal mine working face bracket. Background technique [0002] At present, in the absence of dust prevention measures in the mining working face of our country, the dust concentration of the fully mechanized mining working face can reach 2500-3000mg / m 3 , and the dust situation in the fully mechanized mining face is more serious than that of the general fully mechanized mining face. When the coal mining machine cuts coal, moves the frame and puts the coal in parallel, some coal mines have individual instantaneous original total dust concentrations as high as 8000-10000mg / m 3 . Even if measures are taken, the condition of most of the working faces is still quite bad, and the dust concentration in the downwind direction of the shearer can reach more than 1000 mg / m3 at most, which has seriously exceeded the ...
