摘要
矿井水害的存在对煤矿的安全生产存在严重威胁,我国华北地区煤矿多受奥陶系灰岩水突水威胁,因此在煤田的勘查工作中应重视并做好水文地质工作。本文通过野外调查和钻探等工作手段,完成了焦作方庄煤田普查阶段的水文地质调查,查明了煤层顶底板的水文地质情况,指出了未来矿井充水的来源,确定了煤田主采煤层水文地质勘查类型为底板进水为主的水文地质条件中等的岩溶充水矿床,并为矿山建设和生产提供了供水水源方面的建议。
The mine water disaster has a serious threat to the safety production of coal mines. Most coal mines in North China are threatened by Ordovician limestone water. Therefore, the hydrogeological work of coal mines should be paid attention to and done well in the exploration of coal fields. By means of field investigation and drilling, the hydrogeological survey of Fangzhuang coalfield in Jiaozuo had been completed. The hydrogeological conditions of the roof and floor of the coal seam had been found out, the source of water filling in the future mine had been pointed out. the hydrogeological exploration type of the coal seam was determined as karst water filling deposit with medium hydrogeological conditions, and suggestions on water supply sources for mine construction and production were also provided.
