摘要
矿井水害防治是当前煤层开采的重要工作,是保证煤层安全高效开采的前提。为查明高家堡矿井白垩系含水层水文地质条件,通过地面钻探实测了导水裂隙带高度,采用实测裂采比对其进行预测,利用抽水试验和水化学分析等方法从岩性特征、富水特性、水力联系、水化学特征等方面总结了洛河组含水层水文地质特征。实测导水裂隙带高度为88.03~327.35 m,预测值为92.03~277.13 m,导水裂隙带已经波及到白垩系洛河组含水层。白垩系含水层水文地质条件简单,洛河组含水层对矿井开采威胁较大。
The prevention and control of mine water hazard is an important work of coal seam mining and the premise of ensuring the safe and efficient mining.To find out the hydrogeological conditions of cretaceous aquifer of the Gaojiapu mine,the height of water fissure zone is measured by ground drilling method,and predicted by the measured ratio of fracture:mining.Using pumping test and hydrochemical analysis methods,the hydrogeological characteristics of Luohe Formation aquifer is summarized from aspects of the lithologic characteristics,water enrichment characteristics,hydraulic connection and hydrochemical characteristics.The measured height of the water conduction fissure zone is 88.03~327.35 m and the predicted value is 92.03~277.13 m,which has spread to the Cretaceous Luohe Formation aquifer.The hydrogeological conditions of Cretaceous aquifer are simple,and the aquifer of Luohe Formation is a great threat to mine mining.
