摘要
王行庄煤矿开采二1煤层,目前观测到最高水压2.8MPa,本文通过研究王行庄矿底板隔水层厚度及其阻隔水能力,讨论了充分利用有效隔水层,采用局部实施疏水降压开采等防治水技术的可能性;采用突水系数法及弹塑性力学分析法,论证了王行庄矿谋炭资源带压开采的可行性。
Coalmine mining two 1coalseam of wangxingzhuang coal mine, and the water pressure is 2.8 MPa. We analyzedthe thickness of aquiclude and its waterproof ability, evaluated the water inrush possibility by using water inrush coefficient methodand elastic and plastic mechanical calculation, evaluated the feasibility of mining resource above aquifer.
