2、研究对象,通过分析发现研究区的矿井地质条件较简单裂隙和断层有不同程 度的发育,矿井含水层组由新生界松散砂层孔隙水、二叠系砂岩裂隙水和石灰岩岩溶裂隙 水组成。研究区矿井水的补给来源主要为大气降水、地表水的下渗以及含水层的水通过裂 隙进入矿井。通过详尽水文地质工作,综合认为,矿区内第四系分布少且薄,地形利于自 然排水,地下水补给差,断裂富水性、导水性较弱,含水层裂隙较不发育,富水性弱,矿 床水文地质条件属以裂隙含水层充水为主的简单类型,较易于防治。 关键字关键字:水文地质; 含水层; 充水条件分析 II Abstract In more complex hydrogeological condit
3、ions in underground mines, geological structure through the influence of filling of mine water path, water hydraulic connection, often of mine gushing water amount is formation of a decisive influence. Which not only directly affect the mine drainage scheme design, but also affect deposit exploitati
4、on and utilization plan formulation; therefore, in the mine, to carry out study on controlled mine fault hydrogeology characteristics, on the safe production of the mine, mine resources reasonable development have the important meaning. This paper in Huainan Gu North Mine as the research object, thr
5、ough analysis, it is found that the mine geological conditions in the study area is relatively simple fractures and faults with different levels of development, mine water aquifer is a Cenozoic loose sand pore water, Permian sandstone fissure water and karst fissure water group. The recharge source
6、of mine water in the study area is mainly for atmospheric precipitation, surface water infiltration and containing water of water through the cracks into the mine, recharge boundary mainly limestones and marls outcrop area. Through detailed hydrogeological work. It is concluded that the Quaternary strata in mining area is small and thin, terrain favourable to natural drainage, groundwater recharge, rich water fault, water is weaker,
