摘要
朝川矿区岩溶水是一个相对独立的水文地质单元,张村井田靠近西南部寒武系灰岩露头的补给区,在岩溶水系统的补给—径流带上,受寒灰露头补给影响,存在寒灰高水位异常区域。高水位异常区域的存在严重影响张村矿采区规划和采掘正常合理布置,高水位异常必须查明。张村矿通过多种手段及方法客观查明矿井水文地质状况,在借鉴相邻矿井疏水降压经验的基础上,经过分析、论证,决定实施疏水工程并制定疏水工程措施,以确保工程施工安全。
Chaochuan karst mining water is a relatively independent unit of the hydro-geological, Zhangcun mine field is near to the southwest of Cambrian limestone outcrop recharge areas,it is also situated on the supply-to bring runoff zone of karst water system. Affected by cold gray outcrop recharge. Zhangcun Mine have the existence of cold gray high-level abnomal area. Cold abnormal regions influenced normal mining work, so high-level abnomal area must be identified. Through various means and methods, based on learning from adjacent mine,the hydrogeological conditions of the mine were identified. According to certain analysis and demonstration, decided to implement the hydrophobie project and relevant measures to ensure construction safety.
