摘要
通过对三交河矿下组煤系统巷涌水资料整理,结合三交河矿K2含水层区域水文地质条件,分析了三交河矿K2含水层的补给、径流关系。预测三交河矿西侧K2含水层静储量约60 m3/h;下组煤采掘过程中顶板涌水量不大于300 m3/h;掘进巷道整体揭露、疏放K2含水层后,回采期间K2含水层将不构成安全威胁。
The data of water gushing of lower group coal were combined with the hydrogeological condition of K2 aquifer zone to analyze the supply and runoff of the aquifer in Sanjiaohe mine. The study predicts that statie-storage is around 60m^3/h in the aquifer and the water gushing is not more than 300m^3/h in the process of driving. The overall opening of the roadway and the drainage of the K2 aquifer ensure that the aquifer will not pose a threat on the mining.
