山西省霍州矿区水文地质条件及矿井充水条件分析

Analysis of Hydrogeological Conditions and Water Filling of Mine

山西省霍州矿区是全国少有的低硫焦煤基地之一,由于矿区处于郭庄岩溶水系统的径流带和排泄区,地下水富水性强,矿区水文地质条件复杂,加之构造十分发育,断裂构造平均91条/km2,陷落柱平均60个/km2,水害类型复杂多样。随着开采水平的不断延伸和开采深度的不断加大,多数矿井带压开采,最大承压6.1MPa,矿井受水害威胁程度也越来越大。依据其水文地质条件,将其充水类型划分为四种类型,以及四种导水方式,并确定了该区含水岩层的富水性。

The Huozhou mining area in Shanxi Province is one of unwonted low sulfur coking coal bases in the country. Since the mining area is situated at runoff and discharge zones of Guozhuang karstic water system with strong water yield property, thus the hydrogeological condition is complex, average fault distribution is 91per km2, subsided column 60 per km2, so mine water disaster has many types. Along with the deepening of mining level, many mines have to mining under safe water pressure of aquifer and the maximum pressure is 6.1MPa, and the water disaster threatening getting greater and greater. Based on hydrogeological condition, the paper divided 4 water rifling and 4 water conducting types, defined water yield property of water-bearing strata in the area.
