摘　　要：鸟山煤矿是鹤岗矿区深部煤炭资源勘探开发的优先领域,开采深度在700~1200m。为对鸟山煤矿水文地质条件进行研究,对水文地质物探、钻探、抽水试验、分析化验等成果进行了综合分析,结果表明:井田内主要充水含水层为下白垩统石头庙子组含水层层、石头河子组含水层。其中,下白垩统石头庙子组砾岩裂隙含水层为对煤层开采影响较大的充水含水层,富水性中等—强,富水异常区大部分位于断裂构造破碎带附近。下白垩统石头河子组砂岩裂隙含水层为直接充水含水层,富水性弱,在断层对接部位与石头庙子组砾岩含水层之间存在水力联系。石头庙子组含水层上覆为东山组,东山组底部存在分布不稳定的致密粉砂岩隔水层,透水性较弱,隔水能力弱;石头河子组煤层间泥页岩、粉砂岩与局部不可采煤层组成软硬相间岩组合,为相对隔水层,下部泥页岩与粉砂岩渗透性差,隔水性较好。Niaoshan Coal Mine is a priority area for the exploration and development of deep coal resources in the Hegang mining area,with a mining depth of 700~1200m.In order to study the deep hydrogeological conditions of the Niaoshan Mine,this article has carried out a comprehensive analysis of the results of hydrogeological and geophysical prospecting,drilling,pumping tests,analytical tests,etc.The results show that the main water-filled aquifer in the minefield is the Shitoumiaozi Formation of the Lower Cretaceous System Aquifer,Shitouhezi aquifer.Among them,the conglomerate fractured aquifer of the Shitoumiaozi Formation of the Lower Cretaceous system is a water-filled aquifer that has a great impact on coal seam mining,with medium to strong water richness,and most of the water-rich abnormal areas are located near the fractured fracture zone.The sandstone fractured aquifer of the Shitouhezi Formation in the Lower Cretaceous system is a direct water-filled aquifer with weak water richness.There is a hydraulic connection between the fault butt and the conglomerate aquifer of the Shitoumiaozi Formation.The aquifer of the Shitoumiaozi Formation is overlaid by the Dongshan Formation.At the bottom of the Dongshan Formation,there is an unstable tight siltstone impermeable layer with weak water permeability and weak water resistance.The interbed shale and siltstone of the Shitouhezi Formation and The partially unmineable coal seams consist of a combination of soft and hard interphase rocks,which are relatively water-resistant layers.The lower shale and siltstone have poor permeability and good water resistance.
