煤矿矿井水净化处理与回灌治理技术

Water Decontamination and Recharge Treatment in Coalmine

摘要:

煤矿在开采煤炭的同时，会有大量的矿井污水排到地面，造成环境污染。为解决矿井水排放的污染问题,施工大口径回灌井和建造地面水净化处理厂，矿井水经处理后部分用于煤矿生产，多余部分通过回灌井注入地下，实现水资源循环利用和节能减排。通过梧桐庄矿工程实例，介绍了煤矿矿井水净化处理与回灌治理技术。

Abstract:

Large amount of wastewater is discharged to the ground surface in coal mining with environment pollution. Large-diameter recharge well and water decontamination plant are constructed to solve the problem. After the treatment, part of mine drainage is used in coal production and the rest is injected into the ground through recharge well to realize water resource cyclic and energy-saving & emission reduction. With the project case of Wutongzhuang mine, the water decontamination and recharge treatment are introduced.
