目前,我国煤矿井下年排放矿井水达45亿立方米,利用率为43.8%,远低于发达国家80%左右的标准,大量排放的矿井水不仅造成环境污染,也造成了水资源的浪费。矿井水的主要来源是大气降水,还有一部分来源于地表水、断层水、含水层水、采空区水,那么如何让这些水资源变废为宝?本文就矿井水资源现状以及矿井水处理技术做一浅谈。一、矿井水资源的种类矿井水的基本水质与当地地下水水质相同,但由于流经采
At present, China’s coal mine discharges 4.5 billion cubic meters of underground mine water annually, with a utilization rate of 43.8%, far below the standard of about 80% in developed countries. The large amount of discharged mine water not only causes environmental pollution but also causes waste of water resources. Mine water is the main source of atmospheric precipitation, but also part of the surface water, fault water, aquifer water, goaf water, then how to make these water resources turning waste into treasure? This paper on the status of mine water resources and mine water treatment Technology to make a talk about. First, the type of mine water The basic water quality of mine water and local groundwater quality the same, but because of the flow of mining
