解析法在带压开采疏干涌水量预测中的应用

根据历年涌水量资料和大型群孔放水试验资料对刘桥二矿矿区的水文地质条件进行分析,并结合目前各涌水量预测方法原理和应用条件,采用解析法对带压开采下煤层太原组灰岩含水层疏干涌水量进行了预计.在建立预测模型、选择合适的参数进行求解后,认为太原组灰岩含水丰富,生产中应加以防范.

Application of Analytical Method for Water Flow Prediction of Draining with Mining Under Safe Water Pressure of Aquifer

Based on the existing information and drainage hole test data,the hydrogeology condition of area of Liuqiao No.2 Mine was analyzed,dewatering quanlity of Taiyuan limestone aquifer was predicted using analytical method with mining under safe water pressure of aquifer combined with the principle of current water flow predicting methods and their application conditions.With the condition of establishing prediction mode and choosing reasonable parameters,the author believed that,Taiyuan limestone aquifer has rich water,and it should be paid attention to in production.
