陕西省红石岩煤矿水文地质条件及防治水措施

Hydrogeological conditions and water control measures of Shaanxi Hongshiyan Coal Mine

根据陕西省红石岩煤矿已有的钻探、物探和水质化验及生产揭露的地质资料,分析了矿井的地质条件和矿井水文地质条件,结合近3年矿井涌水量观测数据,认为矿井的直接充水水源是煤层顶板砂岩裂隙水和老空积水及因采动影响产生的导水裂隙带进入井下的大气降水和地表水,主要充水通道为导水裂隙带和老窑巷道,主、副井筒周边采空区积水和四采区采空区积水是矿井的主要水患,并提出了针对性的防治水措施,以确保矿井安全生产。

Based on the existing geological data of drilling,geophysical exploration,water quality test and production exposure in Shaanxi Hongshiyan Coal Mine,the geological conditions and hydrogeological conditions of the mine were analyzed.According to the observation data of mine water inflow in recent three years,it is considered that the direct water filling source of the mine is the sandstone fissure water of the coal seam roof,the water accumulation in the old goaf and the atmospheric precipitation and surface water entering the mine through the water diversion fracture zone,the main water filling channel of the mine is the water diversion fracture zone and the roadway of old coal mines,and the main water hazard of the mine is the goaf water around the main and auxiliary shafts and the goaf water of the fourth mining area.In order to ensure the safety of mine production,the corresponding water control measures were put forward.
