摘要
针对矿井地下水的大量涌出造成的开采难度增大,严重威胁矿工生命安全等问题,在详细分析唐山矿矿床水文地质条件的基础上,运用Visual Mod Flow数值模拟法和大井法预测了5煤顶板含水层的涌水量,并与煤矿现有涌水量进行对比,结果显示数值模拟预测的涌水量更具准确性,从而为矿井的安全开采提供保障。
Aiming at the serious influence of water inrush hazard on coal mine production, and the threat on personnel safety, the paper applied large well method and numerical simulation to predict the water inflow of No. 5 coal seam roof aquifer in Tangshan Coal Mine based on detailed analysis of the hydrogeological conditions, the results were compared with the actual water inflow. The comparison showed that, numerical simulation could improve the water inflow prediction accuracy, and provide protection for coal mining safety.
