摘　　要：针对许家岭进风井井筒需快速揭3#煤层,因地制宜采用井筒、井下立体式预抽揭煤区域煤层瓦斯,解决了揭煤抽放时间较长问题,取得了井筒快速揭煤效果,为类似条件的揭煤工作积累了丰富的实践经验[1]。In view of the need to quickly uncover No.3 coal seam in the shaft of Xujialing intake shaft,according to local conditions,the wellbore and underground three-dimensional pre-drainage of coal seam gas is used to solve the problem of long time of gas drainage,and the effect of rapid coal uncovering in the shaft is obtained,which has accumulated rich practical experience for coal uncovering under similar conditions.

关 键 词：立体式 井筒 揭煤
