摘　　要：为解决某矿30902工作面回采巷道掘进期间面临顶板涌出量大问题,提出采用长距离顶板钻孔对巷道顶板含水层进行超前探测及疏排,并针对局部顶板富水区采用中空注浆锚杆进行改造、加固。现场应用后,30902工作面回采巷道可保持20 m/d掘进速度,期间巷道顶板淋水量控制在3 m^(3)/h以内,巷道掘进基本不受顶板淋水影响,取得较好的防治水效果。In order to solve the problem of large amount of roof gusher during the excavation of 30902 working face in a mine,it is proposed to adopt long distance roof drilling to detect and drain the aquifer of roof in advance,and adopt hollow grouting bolt to transform and reinforce the local water-rich area of roof.After the field application,30902 working face mining roadway can maintain the driving speed of 20 m/d,during the tunnel roof water leaching control within 3 m^(3)/h,tunnel driving is basically not affected by the roof water leaching,achieved good water control effect.
