摘　　要：本文对山西古县金谷煤业有限公司的地质与水文地质条件进行分析研究,查明矿井主要充水因素,包括大气降水及地表水、含水层水、采空区积水等。通过现场实测和数据分析,确定了各含水层的水文特征及其与矿井充水的关系,计算了垮落带和导水裂隙带高度以及奥灰水突水系数。在此基础上,采用面积比拟法对矿井涌水量进行了预测,得出矿井正常涌水量为54.58 m^(3)/h,最大涌水量为81.87 m^(3)/h。这一研究为金谷煤业矿井水害防治提供了科学依据,有助于提高矿井的安全生产水平,对于类似地质条件下的煤矿充水因素评价与涌水量预测具有重要的参考价值。This paper analyzed and studied the geological and hydrogeological conditions of Jingu Coal Industry Co.,Ltd.in Guxian County,Shanxi Province,and found out the main water filling factors of the mine,including atmospheric precipitation and surface water,aquifer water,goaf water and so on.Through field measurement and data analysis,the hydrological characteristics of each aquifer and its relationship with mine water filling were determined,and the height of caving zone and water flowing fractured zone and the water outburst coefficient of Ordovician limestone water were calculated.On this basis,the area comparison method was used to predict the mine water inflow,and the normal mine water inflow was 54.58 m^(3)/h,and the maximum water inflow was 81.87 m^(3)/h.This study provided a scientific basis for the prevention and control of mine water disasters in Jingu Coal Industry,which was helpful to improve the safety production level of the mine.It had important reference value for the evaluation of coal mine water filling factors and the prediction of water inflow under similar geological conditions.
