| 摘 要： | 根据王家岭井田地质、水文地质条件,提出了井田内上马家沟组岩溶含水层应属富水性中等-强含水层。采用关键层理论及突水系数法,研究了王家岭煤矿开采2号煤层时的充水因素及顶底板突水危险性。通过对煤层顶板的基岩风化裂隙水及采空积水的分析,对2号煤层底板太原组和上马家沟组灰岩岩溶水突水系数进行了计算。结果表明：井田南部2号煤层,雨季时基岩风化裂隙水对煤层开采有较大影响;201、202、204、206采区南部为采空积水透水危险区;201、202采区为太灰突水危险区和奥灰突水相对危险区,其他采区为相对安全区或安全区。

| Abstract: | According to the geological and hydrological conditions of Wangjialing Minefield,the karst aquifer in the Up Majiagou Group within the minefield would be a watery middle and high aquifer.The key stratum theory and the water inrush coefficient method was applied to study the water filling factors and the water inrush danger during the No.2 seam mining in Wangjialing Mine.With the analysis on the weathered crack water of the base rock in the roof above seam and the water accumulated in goaf,a calculation was ... |
