皖北前常矿水文地质特征及矿井涌水量预测

Prediction of mine water and hydrogeological feature of Qianchang Mine of Northern Anhui

基于以往的地质资料,分析了前常矿水文地质特征,利用"比拟法"和"解析法"对矿井涌水量进行预测分析。研究结果表明,研究区主要充水含水层富水性弱至中等,地下水补给条件相对较差,但岩溶裂隙含水层水性较强,且断裂带等导水通道存在一定的安全隐患;研究区深部开采矿井正常涌水量为520 m^3/h,最大涌水量为662 m^3/h。

Based on former geological data and hydrogeological feature of Qianehang Mine, analogue method and analytical method were used to predict mine inflow. The results showed that major aquifer water in research area was weak to moderate, and it was in a bad condition of groundwater recharge. But water of karst fissure aquifer was strong and potential safety hazard existed in underground watercourse of fault zone. Normal water inflow in deep mining was 520 m^3 / h, and maximum water emission was 662 m^3 / h.
