Abstract: In view of the difficulty of dust control caused by the diffuse diffusion of dust carried by the compressed air flow in the driving face of rock roadway,a comprehensive dust control scheme of "wind control-purification" was put forward, and an efficient dust removal system for the driving face of rock roadway was constructed,which consisted of a wet cyclone dust collector,an easy-to-assemble and disassemble dust control device and a portable negative pressure air duct. The influence of different installation schemes of the dust removal system on the dust removal effect was compared and analyzed. Considering the dust removal effect and labor intensity,the best installation scheme of wet cyclone dust collector and the best installation position of negative pressure air duct and dust control device are determined. The field application in the driving face of rock roadway in a mine auxiliary transportation roadway shows that when the negative pressure air duct is installed at the opposite side of the ventilation ram,the dust suction port is 3 m away from the roadway head-on,and the dust control device is 5 m behind the air pressure port of the ventilation ram,the high-concentration dust in the head-on is controlled near the head-on under the combined action of the air pressure of the ventilation duct,the air control of the dust control device and the dust extraction of the dust collector,and continuously moves to the dust suction port of the negative pressure duct,and is finally sucked into the dust collector for purification. The dust removal efficiency of total dust and respirable dust in front of the dust collector is above 95. 9% and 94. 9% respectively,and the dust removal efficiency of total dust and respirable dust in the back of the dust collector is above 96. 5% and 95. 4% respectively,which significantly improved the visibility of the roadway and effectively solved the dust control problem caused by ventilation in rock roadway driving face.
