回注井与矿井水处理

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。

Recharge Wells and Mine Water Treatment

To settle mine water discharge resulted pollution on peripheral environment and groundwater quality,conscientiously analyzed mine area hydrogeological data.Reckoned that the Wutongzhuang coalmine is just situated in southeastern end of the Gushan stagnant area,a basically enclosed horst block,the aquifer there is at a standstill,and provided with natural geologic structural condition for recharge and storage highly mineralized mine water.To drill large diameter reinjection wells in selected area,take the up to the standard mine water after multistage processing by surface water treatment plant classed and dispatching through pipe network to uses,recharge and storage for mine production,living and agricultural irrigation.The technology has unbound 39 million tons of coal resources,realized water resource recycle and carried energy conservation,emission reduction and ecological environment preservation points.
