伊川县万安山采石场矿山地质环境修复治理研究

Study on mine geological environment restoration treatment of Wan′an Mountain Quarry in Yichuan County

废旧矿山生态地质环境破坏严重,严重阻碍了当地经济社会的发展。矿山因开采形成采坑8处,周边高陡边坡分布了大量危岩体,当雨季出现时极易发生崩塌地质灾害,同时,废弃采坑和高陡边坡对矿区地形地貌景观也造成了严重的破坏。采取边坡修整工程、场地平整工程、排水沟工程、垫渣和覆土工程、生物工程等修复矿山地质环境问题。通过矿山修复整治等,消除了地质灾害隐患,改善了矿区地貌景观,减轻了对土地及地下水资源破坏,改善了矿区及周边生产生活环境,恢复耕地16.46 hm^(2)、草地3.37 hm^(2)、林地1.63 hm^(2),缓解了矿业开发与环境保护之间的矛盾,有利于人民群众安居乐业和社会稳定。

The ecological and geological environment is seriously damaged by the waste mines,which seriously hinders the development of local economy and society.There are 8 mining pits in the mine due to mining,and a large number of dangerous rock masses are distributed on the high and steep slopes around the mine.When the rainy season occurs,it is easy to collapse geological disasters.At the same time,the abandoned mining pits and high and steep slopes also cause serious damage to the topography and geomorphic landscape of the mine.After discussion,this paper adopts slope dressing engineering,site leveling engineering,drainage ditch engineering,slag padding and soil covering engineering,biological engineering and so on to repair the mine geological environment problems.Through mine restoration and renovation,the hidden dangers of geological disasters have been eliminated,the geomorphological landscape of the mining area has been improved,the destruction of land and groundwater resources has been alleviated,the production and living environment of the mining area and its surroundings has been improved,and 16.46 hm^(2)of cultivated land,3.37 hm^(2)of grassland and 1.63 hm^(2)of forest land have been restored,and the contradiction between mining development and environmental protection has been alleviated.It is beneficial for the people to live and work in peace and social stability.
