摘要
通过对赵各庄矿底板隔水层厚度及其阻隔水能力的研究,采用突水系数法及弹塑性力学理论分析法,论证了赵各庄矿深部资源在煤层底板完整、突水系数小于0.15 MPa/m的区段可进行带压开采,创造了我国煤炭资源开采深度-1 200 m的记录.
Based on the study of the thickness and impermeability of coal floor aquiclude, using inrush coefficient method and mechanic method to evaluate the feasibility of mining in deep above aquifer, it is found that mining is feasible in area where the coal floor aquiclude is whole and the inrush coefficient is smaller the 0. 15 MPa/m at - 1 200 m level in zhaogezhuang coal mine, and the depth of mining will make the record in China.
