摘　　要：为提高掘进巷道安全保障能力,以232205工作面运输巷掘进为研究对象,针对顶板含水层涌水给巷道掘进带来的影响,提出布置超前探放水钻孔对含水层进行疏排。依据巷道掘进实际情况,对超前探放水钻孔设计、施工及探放水情况进行分析。现场应用后,232205工作面运输巷掘进期间仅有局部位置出现顶板淋水,淋水量控制在0.3 m^(3)/h以内,其余位置均未出现淋水情况;通过超前探放水,为巷道掘进及围岩支护创造了良好条件。In order to improve the safety guarantee ability of tunneling roadway,taking the tunneling of 232205 working face as the research object,in view of the influence of water gushing from the roof aquifer on the tunneling,an advanced exploration and drainage borehole was proposed to drain the aquifer.According to the actual situation of roadway excavation,the design,construction and water exploration and drainage of advanced drilling holes are analyzed.After field application,during the driving of transportation roadway on 232205 working face,only partial roof water drenching occurred,and the water amount was controlled within 0.3 m^(3)/h,and no water drenching occurred at other positions.It creates good conditions for roadway excavation and surrounding rock support through advance exploration and drainage.
