摘　　要：依托巨野煤田赵楼煤矿地质背景和矿井工程地质资料,分析矿井水文地质特征及充水因素,再结合井下水文观测数据和地质钻孔抽水试验数据,采用大井法和水文地质比拟法对矿井涌水量进行预测。研究表明,矿井内充水水源以上煤组煤层涌水为主,上煤组煤层的直接充水水源为3煤层顶底板砂岩含水层及太原组三灰含水层;结合实际条件,建议采用大井法计算结果,预计矿井正常涌水量为504 m^(3)/h,最大涌水量为756 m^(3)/h。Based on the geological background and engineering geological data of Zhaolou Coal Mine in Juye Coalfield,the hydrogeological characteristics and water filling factors of the mine are analyzed.Combined with the underground hydrological observation data and geological drilling pumping test data,the large well method and hydrogeological analogy method are used to predict the mine water inflow.The research shows that the water filling source in the mine is mainly from the coal seam of the upper coal group,and the direct water filling source of the upper coal group is the sandstone aquifer of the roof and floor of the No.3 coal seam and the three ash aquifer of the Taiyuan group.Combined with the actual conditions,it is recommended to use the calculation results of the large well method.It is estimated that the normal water inflow of the mine is 504 m^(3)/h,and the maximum water inflow is 756 m^(3)/h.
