沁蟒河流域废弃黏土矿矿山生态环境问题及治理对策

Ecological and Environmental Issues and Remediation Strategies of Abandoned Clay Mines in the Qinmang River Basin

沁蟒河流域的黏土矿经过多年的露天开采,导致基岩大面积裸露,废弃的矿渣堆放,造成了严重的水土流失问题,使得当地的生态平衡难以维系。在充分收集已有地质资料的基础上,确定了矿区存在渣坡、高陡边坡和崩塌地质灾害问题。此外,还发现了采坑、废石废渣和平台渣堆对地形地貌景观破坏,以及土地资源破坏和占用等生态环境问题。将治理区分为实质性治理区、辅助措施修复区和纯自然修复区。对实质性治理区和辅助措施修复区实施地质灾害消除、地形地貌平整、覆土工程、植物绿化工程和设立警示牌等举措,有效改善了沁蟒河流域的生态环境,提升了土地资源利用价值,促进了沁阳市经济和社会的可持续发展。

After years of open-pit mining of clay mines in the Qinmang River Basin,extensive bedrock exposure and indiscriminate dumping of waste slag have occurred,causing severe soil erosion and making it difficult to sustain the local ecological balance.Geological hazards,including slag slopes,high and steep slopes,and collapses,have been identified within the mining area.Additionally,it has been observed that mining pits,waste rocks,and platform slag piles disrupt the terrain,landscape,and land resources.The remediation area is categorized into zones for substantive remediation,auxiliary restoration measures,and natural recovery.Soil replacement,vegetation restoration,and the installation of warning signs in the substantive remediation and auxiliary restoration zones have effectively improved the ecological environment of the Qinmang River Basin,enhanced the utilization value of land resources,and promoted the sustainable development of economy and society in Qinyang City.
