摘要
对登封煤田西部矿区煤系地层直接下伏寒武系灰岩含水层的水文地质条件进行调查分析,提出了寒武系地层的层选性、不均一性、各向异性的富水性分布规律和特征,矿区内寒灰水主要以“管道流”为主。针对寒灰水水害特点,提出了防治寒武系灰岩水“浅部以疏为主、中部疏堵结合、深部注浆加固”的具体防治对策及保障措施。
The hydrogeological conditions of the Cambrian limestone aquifer directly underneath the coal-bearing strata in the western mining area of Dengfeng Coalfield limestone were investigated and analyzed,and the water-rich distribution rules of stratigraphy,heterogeneity and anisotropy of the Cambrian strata were proposed and characteristics,the cold gray water in the mining area is mainly"pipeline flow".Aiming at the characteristics of water damage in cold ash water,specific prevention countermeasures and safeguard measures for controlling Cambrian limestone water"mainly sparse in the shallow part,combined with plugging in the middle part and deep grouting reinforcement"are put forward.
