为解决矿井水排放对周边环境和地下水水质的污染,对矿区水文地质资料进行了认真分析,认为梧桐庄矿井位于鼓山东南端的停滞区,属基本封闭的地垒块段,含水层基本处于停滞状态,具备回注储存高矿化度矿井水的地质构造条件。在选定区内建凿大口径回注井组,将经地面水处理厂多级处理后达标的矿井水,通过管网系统分级配送利用、回注储存,用于矿井生产、生活及农田灌溉。该工艺技术解放煤炭资源3 900万t,实现了水资源循环利用,达到了节能减排,保护生态环境的目的。
In order to solve the pollution of mine water discharge to the surrounding environment and groundwater quality, the hydrogeological data of the mining area were carefully analyzed. It is concluded that the Wutongzhuang Mine is located in the stagnation zone at the southeastern end of Gushan Mountain and is a basically closed basement block with the aquifer basically at a standstill State, with the rebuild storage of high salinity mine water geological conditions. The large-diameter injection well group is built in the selected area, and the mine water that has reached the standard after multi-level treatment by the surface water treatment plant is distributed and utilized by pipe network system for storage and backfill for mine production, living and farmland irrigation . The process technology liberated 39 million tons of coal resources and realized the recycling of water resources, achieving the goal of energy conservation and emission reduction and ecological environment protection.
