在向煤层内打瓦斯抽放钻孔过程中,从钻孔里会涌出大量的煤尘,这些煤尘如果不及时扑捉,散布到空气中随气体流动,被人体吸收后会给人们的身心健康带来危害,平煤集团技术人员大胆尝试,经过技术研究及实验,设计出了矿用湿式螺旋扑尘器,该设备投入生产使用后,取得了良好的使用效果,值得在全煤系统推广应用。 During the process of gas drainage drilling into the coal seam, a large amount of coal dust gushes out from the borehole. If these coal dusts are not caught in time, they are dispersed in the air and flow along with the gas, which are absorbed by the human body and give people Physical and mental health hazards, Pingmei Group technicians bold attempt, after technical research and experiments, designed a mine wet spiral dust collector, the device put into production and use, and achieved good results, it is worth in the whole coal system Promote the application.
