摘　　要：3上502工作面为高煤公司首个提限工作面,靠近煤层露头,上覆基岩依次为山西组砂岩、第四系松散层,富水性强,预计工作面回采顶板涌水量大,而上巷无溜煤眼,下巷无法布置泄水巷,抗突水能力差。采用仰上钻孔精准疏放顶板含水层水,降低水压,在消减工作面回采突水量、突水强度和峰值方面发挥了重大作用,极具应用推广价值。The 3upper 502 face is the first lifting limit face of the high coal company,near the coal seam outcrop,the overlying bedrock is followed by Shanxi formation sandstone,Quaternary loose layer,rich in water,it is expected that the face mining roof water inflow is large,but there is no coal hole in the upper roadway,the lower roadway can not be arranged drainage roadway,the ability to resist water inrush is poor.It has played an important role in accurately draining the water of roof aquifer,reducing water pressure,reducing water inrush,strength and peak value in mining face,which has great application and promotion value.
