摘　　要：金鹅池煤矿在+200 m东轨道石门施工探水钻孔时发生突水,涌水量从最初的80 m3/h短时间内迅速增大至320 m3/h,持续3个多月涌水量达到200 m3/h以上。从水量、水质、顶板基岩导含水结构、补给来源及水力联系等方面,对顶板强岩溶裂隙突水特征进行分析、判别,并在物探及注浆堵水中得以验证。根据验证结论,对矿井水文地质特征作出进一步修正,为矿井开拓部署调整及开采预控提供科学依据。Water inrush occurred when water prospecting holes were drilled in east ginny cross-cut at＋200 m level in Jin＆#39;echi Coal Mine, the water inflow rate quickly increased from the original 80 m3/h to 320 m3/h in a short period of time, with water quantity up to 200 m3/h and lasting for more than three months. In this paper, analysis and discrimination were made on the inrush characteristics of the roof karst fissure make-up water from the aspects of water quantity, water quality, the water-flowing and water-bearing structure of roof rock stratum, the make-up water source, the hydraulic connection, etc. and verification was carried out through geophysical prospecting and block up water grouting. Based on the verification results, the mine hydro-geological characteristics were further corrected, this thus provided scientific basis for the adjustment of the mine development layout and the prevention and control for mining.
