摘要
井田5(4+5)号煤层奥灰水全区带压,存在奥灰水突水可能性。通过对回采过程中矿山压力对煤层底板破坏分析、掘进巷道过程中底板突水安全性分析、采用突水系数法对煤层底板安全性分析,来说明奥灰水对井田5(4+5)号带压开采的影响。
Due to mining above aquifer in No.5（4＋5） coal seam, inrush of Ordovieian limestone water might happen. We analyzed the floor failure caused by mine pressure in the caving, the safety of floor water-irruption in the driving roadway, and the floor safety with water inrush coefficients to illustrate the effects of the Ordovieian limestone water on the mining above aquifer.
