摘要
地下水加坡理论可有效的消除抽水试验引起的无效降深,结合云驾岭煤矿井筒检查孔抽水试验资料,对该井筒检查孔涌水量进行了预算,预算副井筒P2s4砂岩含水层涌水量为523.03m3/h,实际涌水量为455m3/h,误差率14.95%,可见运用加坡理论计算的矿井涌水量与井筒实际涌水量基本相符。
The groundwater slopping theory can effectively eliminate invalid drawdown caused by pumping test, on the basis of Yunjialing coalmine pilot hole shaft pumping test data, to estimate pilot hole water inflow. Estimated auxiliary shaft P2S4 sandstone aquifer water inflow is 523.03m^3/h, actual measured water inflow 455m^3/h, error rate 14.95%. It is obvious that mine water inflow estimated through slopping theory is basically conforming to practical mine inflow.
