矿井涌水量预测及水文地质类型划分

Prediction of Water Inflow and Division of Hydrogeological Types in Mine

矿井涌水量预测及水文地质类型划分对矿井防治水具有重要意义。以山西A煤矿为试验矿井,对矿井涌水量进行分析和评价,并对矿井水文地质类型进行划分。研究结果表明:矿井涌水量受季节影响不大,矿井涌水量的增加主要受新进入矿井的水控制;从2015—2019年涌水量动态曲线可看出,矿井仍处于消耗静储量状态,并有逐渐趋于稳定的趋势;矿井涌水量正常涌水量为291.1 m^(3)/h,最大涌水量为378.4 m^(3)/h;煤矿开采的3#煤层水文地质类型应划分为中等类型。

The prediction of mine water inflow and the division of hydrogeological types are of great significance for mine water control.Taking Coal Mine A in Shanxi as a test mine,the mine water inflow was analyzed and evaluated,and the hydrogeological types of the mine were divided.The results showed that the mine water inflow was nearly not affected by the season,and the increase of mine water inflow was mainly controlled by the new water entering the mine;from the dynamic curve of water inflow from 2015 to 2019,it can be seen that the mine was still in the state of static reserve consumption,and had a tendency to gradually stabilize;the normal water inflow of the mine was 291.1 m^(3)/h,and the maximum water inflow was 378.4 m^(3)/h;the hydrogeological type of 3#coal seam in coal mining should be divided into medium type.
