摘要
在概述新阳煤矿矿井水文地质条件的基础上,对矿井下组煤开采充水因素进行了分析,指出了下组煤开采主要充水来源为煤层顶板砂岩裂隙及岩溶裂隙水、煤层底板奥灰岩溶水以及采空区积水。其矿井充水通道主要为断裂构造发育地段的断层和陷落柱以及采煤形成的导水裂隙。针对下组煤矿井水害特征提出了防治水相关措施。
Based on the introduction of hydrogeological condition of Xinyang Coal Mine, analyzes the factors of water filling in the mining of lower coal group, and points out that the main water filling source in the mining of lower coal group is coal roof sandstone fissure and karst fissure water, Ordovician karst water of coal seam floor and goaf seeper. The main channel of mine water filling is the water-conducting crack formed by fault and subsided columns in fault structural fracture zone and coal mining. Water prevention and control measures are put forward according to the characteristics of coal mine water disaster of lower group.
