摘　　要：鹤煤矿区现有三矿、中泰矿业、六矿、八矿、九矿五对生产矿,水文地质条件相似。近年来,各矿均进入了井田深部生产,都面临着煤层底板高承压岩溶水的突水隐患。本文通过分析矿区水文地质条件及岩溶特征,研判突水规律及其原因,总结承压水突水影响因素及特征,提出以深部补充勘探、划分三区、超前探查、注浆加固、安全评价、带压开采技术措施为技术手段的承压水害防治技术路线。There are five pairs of production mines in He coal mine area,namely No.3 Mine,Zhongtai Mining Co.,Ltd.,No.6 mine,No.8 mine and No.9 mine,with similar hydrogeological conditions.In recent years,each mine has entered the deep production of the mine field,and will face the hidden danger of water inrush from the high pressure karst water in the coal seam floor.Based on the analysis of hydrogeological conditions and karst characteristics in the mining area,this paper studied and judges the law and causes of water inrush,summarized the influencing factors and characteristics of water inrush from confined water,and put forward the technical route for prevention and control of confined water disaster by means of deep supplementary exploration,division of three areas,advanced exploration,grouting reinforcement,safety evaluation and mining under pressure.
