摘　　要：鹤岗矿区新陆煤矿主要充水含水层为白垩系石头庙子组砾岩裂隙含水层与石头河子组砂岩裂隙含水层,石头庙子组含水层富水性强,石头河子组含水层距离可采煤层较近,两含水层均为煤层顶板直接充水含水层,若发生水力联系,将会严重威胁煤矿开采。在分析矿井水文地质条件的基础上,从水化学特征、水位、隔水层、断层影响区地面瞬变电磁特征等方面对两含水层特征进行综合对比分析,得出了两含水层一般区域水力联系弱,在断层影响区域水力联系相对强的规律,为煤矿防治水工作提供了重要参考依据。The main water filling aquifers in the Xinlu coalmine, Hegang mining area are Cretaceous Shitoumiaozi Formation conglomer- ate fissured aquifer and Shitouhezi Formation sandstone fissured aquifer. The former has strong water yield property, while the later is nearer the main mineable coal seams, thus both direct water filling aquifers; if hydraulic connection existed will seriously threaten coal mining. Based on mine hydrogeological condition analysis, carried out integrated comparative analysis from aspects of hydrochemical features, water level aquifuge, fault impacted area surface TEM features of the two aquifers. The result has considered that the regional hydraulic connection of two aquifers generally weaker, but stronger in fault impacted area, thus provided important reference basis for coalmine water control works.
