为了准确预计招贤煤矿矿井涌水量,正确地指导煤矿安全生产,在分析矿井水文地质特征的基础上,运用"大井法"、集水廊道法与比拟法对该矿井涌水量进行了计算,对该矿井工作面顶板的涌水量进行了预测,计算出静储量,给出了离层积水均匀下泄时的涌水量计算方法和公式,通过比拟法确定了灾变涌水量。研究结果表明:工作面采前疏放水工程对顶板含水层有效疏放和不考虑离层积水条件下,1307工作面正常涌水量为110.33 m~3/h,最大涌水量为584.12 m~3/h;考虑离层积水均匀下泄的涌水量为249 m~3/h;考虑离层积水的灾变涌水量为1 100 m~3/h,该研究结果为煤矿防治水提高预测的可靠性与准确性。

In order to accurately predict a mine water inflow of Zhaoxian Mine and to correctly guide the safety production of the mine,based on the analysis of the mine hydrogeological features,the "big well method",water collection channel method and analogy method were applied to the calculation of the mine water inflow and to predict the mine water inflow of the mine roof strata. Static reserves were calculated. The calculation method and equation of the mine water inflow were provided when the separated strata water were evenly discharged. The analogy method was applied to determine the disaster water inflow. The study results showed that a water discharging project before the mining operation of the coal mining face could effectively discharge the aquifer in the roof. With no consideration of the water in the separation strata,the normal water inflow of No. 1307 coal mining face was 110.33 m3/h and the max water inflow was 584.12 m3/h. The water inflow of the separated strata evenly discharged could be considered as 249 m3/h. The disaster water inflow of the separated strata water could be considered as 1 100 m3/h and the study results could improve the reliability and accuracy of the prediction to the mine water prevention and control.
