摘要
随着铁矿石的开采,矿坑涌水量一直是困扰矿山安全的棘手问题。以昌邑东辛庄铁矿区为例,分析地质条件、水文地质条件和地下水的补给径流排泄特征,运用大井法对东辛庄铁矿矿坑进行涌水量预测,为后续矿山露采转地下开采提供依据。预测结果为:第四系孔隙含水层竖井预测正常涌水量2148.76m3/d,预测最大涌水量2578.51m3/d;基岩风化裂隙含水层竖井预测正常涌水量458.97m3/d,预测最大涌水量550.76m3/d;基岩构造裂隙含水层-270m中段预测正常涌水量5098.65m3/d,预测最大涌水量6118.38m3/d。两铁矿之间的-270m运输大巷预测正常涌水量1092.51m3/d,预测最大涌水量1311.01m3/d。
With iron ore mining operation, yield water of mine has always been a thorny issue that has plagued mines safety. Based on Dongxin iron mine in Changyi as an example, analysis the conditions of geological, hydrogeological conditions and recharge of groundwater runoff drainage conditions, using large water forecasting method for iron ore mines. Forecast results are that the shaft of porous aquifer in quaternary normal water inflow is 2148.76m3/d and the largest water inflow is 2578.51m3/d. The shafts of fissure water aquifer in weathered bedrock normal water inflow is 458.97m3/d and the largest water inflow is 550.76m3/d. The shafts of fissure water aquifer in the middle of-270 m tectonic bedrock normal water inflow is 5098.65m3/d and the largest water inflow is 6118.38m3/d.
