压风水力喷雾降尘,是压风与压水一起从喷嘴喷出,形成高密度雾滴的一项矿山降尘技术。苏联七十年代开始推广,现正被作为常规防尘技术手段。卡垃干达矿区煤层的平均产尘能力达 20毫克/焦耳,应用这一技术十年,采掘工作面内的粉尘浓度降低一半,从而使尘肺发病人数减少 75%。 经对除
Pressurized water jet dust, is the wind pressure and water jet together from the nozzle, the formation of high-density droplet mine dust technology. The Soviet Union started its promotion in the 1970s and is now being used as a routine dust-proof technique. The average dust generation capacity of the coal seam in the dry coal mine reaches 20 mg / joules. With this technology, the dust concentration in the mining face is reduced by half by using this technology and the number of pneumoconiosis patients is reduced by 75%. After the right addition
