摘 要:为解决煤矿开采过程中通风量不足和瓦斯爆炸等问题,深入研究煤矿工作面通风系统设计与瓦斯灾害防治方法。通过新增回风巷设计、合理选择支护方式和进行风量测量等,风量显著增加,特别是二采区轨道巷与运输巷风量增加了约220 m^(3)/min。同时,采用抽采为主、通风稀释为辅的瓦斯灾害防治方式,瓦斯浓度显著降低,抽采率达到42%,确保了煤矿工作面的高效生产。In order to solve the problems of insufficient ventilation,gas explosion and so on in the process of coal mining,the ventilation system design and the gas disaster prevention and control methods in coal mine working face are deeply studied.Through the design of new return airways,reasonable selection of support forms and air volume measurement,the air volume has been significantly increased,especially the air volume in track roadway and transportation roadway in the second mining area has been increased by about 220 m^(3)/min.At the same time,by adopting the gas disaster prevention and control methods which are mainly based on drainage and supplemented by ventilation dilution,the concentration of gas has been significantly reduced,and the drainage rate has reached 42%,which ensures the efficient production of the coal mine working face.
