Shaanxi Binchang Mining Group Co., Ltd.

彬长矿区水文地质条件复杂,区内多对矿井水文地质类型均为复杂型,矿井开采均不同程度受到水害影响。通过对各矿井已有地质、水文地质资料及回采期间的揭露情况分析,认为目前彬长矿区各矿井主要水害为巨厚型中等富水洛河组砂岩含水层水,此含水层可通过露头区接受大气降水补给,同时接受区域侧向径流的补给,补给条件良好。运用多种方法和理论对彬长矿区水文地质条件进行分析评价,研究涌水主控因素特点及表现形式,并进一步掌握矿井涌水规律,有助于全面认识矿井水文地质条件和受水害影响程度,是做好煤矿防治水工作的水文地质依据,能够促使煤矿通过采取有效的防治水措施,保障矿井的安全生产。

The hydrogeological conditions in Binchang mining area is complex, there are many mines of hydrogeological conditions are complex, the mining of the mines are affected by water hazards to varying degrees. According to the analysis ofthe existing geological and hydrogeological data of each mine and the exposure during mining, the main water hazards of themines in Binchang mining area is the huge thick medium water rich Luohe Formation sandstone aquifer water, which can berecharged by atmospheric precipitation through the outcrop area, and receive the recharge of regional lateral runoff at thesame time, and the recharge conditions is good. Using various methods and theories to analyze and study the hydrogeologicalconditions of Binchang mining area, study the characteristics and manifestations of the main control factors of water inflow,and further master the law of mine water inflow, which is helpful to comprehensively understand the hydrogeological conditions of the mine and the extent of the impact of water hazards, it is the hydrogeological basis for doing a good job of waterprevention and control in the coal mine, and can promote the coal mine to take effective water prevention measures to ensurethe safe production of the mine.
