摘要
利用井下移动空压机形成独立供风系统的中压空气钻进方法是解决松软突出煤层钻孔难题的有效途径。为解决钻进过程中的粉尘污染问题,研制了多级无动力除尘装置,在松软煤层中风压空气钻进现场应用中取得良好的使用效果。
Forming an independent air supply system with the movable underground air compressor,the moderate pressure compressed air drilling is an effective method to solve the drilling difficulty in the soft coal seam.Multistage unpowered dust collector was designed to solve the problem of dust pollution.Effective result is acquired in the site use.
