基于地下水井流理论,通过大型干扰井群放水试验,查明了淮北矿区某矿6煤底板太原组石灰岩含水层的富水性、补径排条件及其与下伏奥陶系石灰岩含水层的水力联系,在此基础上运用FEFLOW软件对该矿太原组石灰岩含水层的流场演化规律进行了数值模拟。结果表明,该矿太原组石灰岩含水层径流条件较好,岩溶相对发育,且富水性不均一,与下伏奥陶系石灰岩的水力联系极其微弱,区内孟口断层阻水有差异性,自北向南部隔水性变差。
Based on the theory of groundwater flow and well water discharge, the water-richness of limestone aquifers in the Taiyuan Formation of 6 coal seam in a mine in Huaibei Mining Area, and the conditions of compensation and drainage and its relationship with hydraulic characteristics of the underlying Ordovician limestone aquifer On this basis, the evolution of the flow field of limestone aquifer in Taiyuan Formation of the mine was numerically simulated by FEFLOW software. The results show that the limestone aquifer in the Taiyuan Formation has good runoff conditions, relatively developed karstification, and rich water-bearing heterogeneity. The hydraulic connection with the underlying Ordovician limestone is extremely weak. North to South impermeability deterioration.
