摘要
我国的矿山地质环境修复工作起步晚,许多未治理的废弃矿山内存在一系列生态环境问题,不仅与周围生态环境不相协调,而且会威胁附近居民生命财产安全。通过野外地质环境调查、地形测量、地质测绘及岩土工程勘察,查明北京密云某矿区存在地形地貌景观破坏、土地资源压占与损毁地质环境问题。地形地貌景观破坏包括开采边坡3处,开采平台1处,采坑1处。采用削坡整形、采坑整治、挡墙等工程措施和绿化措施相结合的方式综合治理,效果良好。
The practice of restoring mine geological environment in China started late. Many untreated and abandoned mines create a series of ecological and environmental problems, which are not only inconsistent with the surrounding ecological environment, but also threaten the safety of the life and property of nearby residents. Through field geological environment survey, topographic survey, geological surveying and mapping, and geotechnical engineering survey of a mining area in Miyun, Beijing, it is found that there are topographic and landscape destruction, land resources occupation and geological environment damage. The topographic and landscape damages occur in 3 mining slopes, 1 mining platform, and 1 mining pit. To curb the problem, a comprehensive management method is applied that combines several engineering measures such as slope cutting and shaping, mining pit improvement, retaining wall and greening. Good effect is achieved as a result.
