摘　　要：针对干式钻孔产生大量粉尘,以及现有除尘装置复杂、笨重等问题,自制了新型干式钻孔除尘装置。通过对装置在仰孔、俯孔和顺层孔地点的现场应用,其全尘除尘效率最高达94.23%,呼尘除尘效率最高达94.06%,钻孔附近区域瓦斯浓度最高减小了约8.1倍,减小了工人的劳动强度及健康危害,提高了瓦斯抽采率。In view of the large amount of dust produced by dry drilling and the complexity and unwieldiness of existing dust removal devices,a new dry drilling dust removal device is made.Through the field application of the device in the site of upside-down hole,downside-down hole and downside-down hole,the total dust re⁃moval efficiency of the device is up to 94.23%,the dust call dust removal efficiency is up to 94.06%,and the gas concentration near the borehole is reduced by about 8.1 times,which reduces the labor intensity and health hazard of workers and improves the gas extraction rate.
