深部煤矿闭坑后矿区环境监测及影响分析

Mining area environmental monitoring and impact analysis of deep coal mine after mine closure

煤矿闭坑后若管理不当可能诱发矿区地质及环境灾害,造成严重的经济与生态环境问题,深部煤矿闭坑后的矿区环境污染原因及控制对策应深入研究。以淮北某煤矿闭坑工程为研究背景,首先阐明矿井闭坑原因及现有资源储量,并对矿井闭坑后可能引起的地面沉降、地上及地下水体污染及矿区固体废弃物污染等地质、环境问题进行了详细监测。分析监测数据,得出矿区塌陷区治理、废水、矸石合理利用等治理措施,从而确保矿井闭坑后区域生态环境变化可控,矿区居民生活用水安全可靠。研究成果可为类似深部矿井闭坑后的矿区环境监测及治理工程提供技术参考。

Improper management after coal mine closure may induce geological and environmental disasters in the mining area and cause serious economic and ecological environmental problems.The causes and control countermeasures of environmental pollution in the mining area after deep coal mine closure should be deeply studied.This paper takes the mine closure project of a coal mine in Huaibei as the research background.Firstly, the reasons for the closure of the mine and the existing resource reserves are clarified, and the geological and environmental problems such as land subsidence, pollution of aboveground and underground water bodies and solid waste pollution in the mining area that may be caused by the closure of the mine are monitored in detail.The monitoring data are analyzed to obtain the treatment measures such as the treatment of subsidence area in the mining area, the rational utilization of waste water and gangue, so as to ensure that the change of regional ecological environment is controllable after the mine is closed, and the domestic water of residents in the mining area is safe and reliable.The research results can provide technical reference for mining area environmental monitoring and treatment engineering after mine closure in similar deep mines.
