摘　　要：为提高复杂水文地质条件下煤炭资源利用率和保证承压水上带压开采的安全,采用电剖面法探测了河东煤矿31005工作面10号煤层采后底板破坏深度,根据实测结果计算了一采区不同地点底板突水系数,并利用计算机软件划分出一采区底板突水危险区域。研究结果表明:河东煤矿一采区钻孔崔K-5附近断层构造带突水危险性较大,应加强监测并采取相关安全防水措施。研究结果可为河东煤矿今后底板防治水方案的制定提供重要依据,为落实矿井高效、安全生产提供借鉴。In order to improve coal resource utilization ratio and ensure mining safety over pressure water under complex hydrogeology condition, applying electrical profiling method to surveying floor failure depth after mining 10th eoalseam of 31005 face in Hedong Col- liery. Floor water-burst coefficients of different places were calculated with survey data and water-burst danger area was found by soft- ware. Result showed that water-burst danger in fault tectonic zone near K-5 borehole was large and corresponding water prevention should be adapted. The result could provide important reference for later floor water-burst prevention.
