摘　　要：卧龙湖煤矿北一采区8煤开采顶板涌水量大且持续时间长,对煤矿安全生产和开采效率造成严重影响。这种涌水特点在淮北-永夏煤田顶板水害防治历史上极为罕见,使煤系顶板砂岩水以静储量为主的"疏干型"观念受到挑战。通过开采过程中的水文动态观测、涌水规律和补给水源分析研究,取得了以下成果:(1)北一采区顶板砂岩水初始涌水量大,随时间的延长虽有衰减,但不致疏干,涌水量仍保持在100 m3/h以上的高水平上;(2)随着新工作面的开采,已采工作面的涌水量逐渐转嫁到新开工作面,但新老工作面涌水量之和基本保持稳定;(3)水动态观测成果显示,北一采区涌水量与K3砂岩水位变化之间具有相关性。在弄清涌水规律的基础上,采取煤水分流、隐患排查和超前截流的防治水技术措施,效果显著,可供类似条件下的其他煤矿防治顶板水害时参考。During the extraction of coal No. 8 in the winning district N1, Wolonghu coalmine has large roof water inflow with long duration, thus seriously impacted coalmine safely in production and extraction efficiency. This kind water inflow features are very few in Huaibei - Yongxia coalfield roof water hazard control history, and the original wrong idea of ＂coal measures roof sandstone water is mainly static reserve and easy to be drained＂ has been challenged. Through extraction process hydrogeological dynamic observation, water inflow pattern and water recharge source analysis have acquired following results ： （1） Winning district N1 roof sandstone water initial water inflow is large, although attenuated along with time, but cannot be wholly drained out and remained at above 100m3/h high level; （2） With new face extraction, the water inflow of original face will be gradually migrated to new face, but the total is basically stable ; （2） Water dynamically observed result has shown that the water inflow of winning district N1 and the water level of sandstone K3 is correlated. On the basis of water inrush regular pattern, technical measures of coal and water divergence, hidden hazard investigation and advanced water intercepting have obvious effects and can be as reference for roof water control of other coalmines with similar conditions.
