花岗岩露天关闭矿山生态修复技术应用北大核心CSCD

矿山生态修复是贯彻落实“绿水青山就是金山银山”理念、实施“山水林田湖草沙”生态保护修复工程的重要举措,其中坚硬岩石高陡边坡生态修复是矿山环境修复的难点与热点问题。以苏州市金山浜花岗岩露天关闭矿山生态修复项目为例,调查分析矿山地质环境问题,针对矿山植被覆盖度低、地貌景观破损造成视觉污染及地质灾害现状,采用削坡清坡、浆砌片石格构植被护坡、客土喷播、锚固铁丝网砼筑围堰、废弃地平整覆土、截排水及植被养护等技术对矿山进行生态修复。实践表明:采取的技术方案使花岗岩边坡安全稳定,坡面植被覆盖率达85%以上,废弃地得到整理利用,改善了矿山生态环境和景观面貌,提升了环太湖风景区的生态环境品质。

Application of ecological restoration technology to closed granite open pit mines

Mine ecological restoration is an important measure to implement the new development concept of "Green water and green mountains are golden mountains and silver mountains" and to realize the ecological protection and restoration project of "mountains, rivers, forests, fields, lakes and grasses". Among them, the ecological restoration of hard rock on high and steep slopes is a difficult issue in mine remediation that receives much attention. Taking the closed Jinshanbang granite open pit mine in Suzhou as an example, this paper presents an investigation to geological environment problems of mines. In view of the low vegetation coverage and visual pollution and geological disasters caused by landscape damage, it is suggested to perform ecological restoration by means of slope cutting and slope clearing, mortar rubble lattice vegetation revetment, soil spraying and seeding, iron wire mesh concrete cofferdam construction, waste ground leveling and covering soil, interception and drainage, and vegetation maintenance. Practice shows that the successful application of the technical scheme above makes the granite slope safe and stable, the vegetation coverage ratio of the slope reaches more than 85%, and the abandoned land is sorted and utilized, which improves the ecological environment and landscape appearance of the mine, and enhances the ecological environment quality of the scenic spot around the Taihu Lake.
