基于Q—S曲线法预测工作面涌水量

Prediction of Mine Water Inflow in Working Face Based on Q-S Curve Method

矿井涌水量的准确预测对于防止矿井突水、淹井等矿山恶性事故、降低生产成本、确保矿井安全生产有着重要的理论和实际意义。在梁家矿1111工作面几组抽水试验数据的基础上,模拟了矿井涌水量与水位降深(Q—S)曲线预测法的具体预测过程。在判断曲线方程类型时,分别采用了曲度法、差分法、直线图解法、matlab拟合法,最后用还原检验法对所求曲线方程进行了验证,从而选出了最优方程。

The accurate Prediction of mine inflow growth is of great theoretical and Practical significance for Preventing mine water inrush and flooding accidents,reducing the Production cost and ensuring safe Production of the mine. Based on several grouPs of PumPing test data in 1111 working face in Liangjia Mine,simulation was made on the sPecific Prediction Process with the mine inflow growth and water level drawdown curve（ Q-s）Prediction method. The curvature method,difference method, linear graPhic method and matlab fitting method were resPectively aPPlied for judging the tyPe of the curve equations,then the curve equations were verified with the reduction test method and finally an oPtimal equation was selected from them.
