掘进机作为煤矿巷道掘进的主要设备,在巷道掘进时会产生大量的粉尘。掘进工作面的工序繁杂,产生粉尘的地点位置多变。随着综采、综掘技术的迅猛发展,开采强度不断增大。于此同时,我国煤矿粉尘污染问题日趋严重。如综掘工作面在只采取内外喷雾时,司机处粉尘浓度高达300～1000mg/m3,而且呼吸性粉 Boring machine as a major roadway tunneling equipment, tunneling will produce a lot of dust. Tunneling the face of the complex process, the location of the place dust changes. With the rapid development of fully mechanized and fully mechanized excavation technology, the intensity of mining has been continuously increasing. At the same time, China’s coal mine dust pollution is worsening. If fully mechanized mining face to take only inside and outside the spray, the driver dust concentration as high as 300 ~ 1000mg / m3, and respiratory powder
