露天矿山地质环境修复技术研究——以乌当区照福露天矿为例

近年来,随着矿石类资源不断开发,矿区周围环境遭到破坏,甚至严重影响到地貌景观,违背了“绿水青山就是金山银山”的理念,同时还存在许多地质灾害的隐患,危及人身安全。针对这一问题,以贵州省处于停采状态的乌当区照福露天矿为工程背景,通过现场调查对治理区生态环境进行评估,结合以往工程实践,针对性提出“采坑回填+削坡-岩壁治理-土壤重构+植被复绿-截排水及蓄水”综合治理模式,并以区内矿坑1中局部区段作为主试验点进行应用研究。工程结束后,消除或减轻了矿山地质灾害隐患,为更好地利用区内资源奠定了基础,促进了矿区生态恢复,增加了百姓收入,产生了一定的经济效益。

Study on Geological Environment Restoration Technology of Open-pit Mine:Taking Wudang Zhaofu Open-pit Mine as an example

In recent years, with the continuous development of ore resources, the surrounding environment of the mining area has been destroyed, and even seriously affected the landscape, contrary to the '' green hills are invaluable assets '' concept, but also there are many hidden dangers of geological disasters, endangering personal safety. In view of this problem, taking the Zhaofu Open-pit Mine in Wudang District of Guizhou Province as the engineering background, the ecological environment of the treatment area was evaluated through on-site investigation. Combined with the previous engineering practice, the comprehensive treatment mode of " mining pit backfilling + slope cutting-rock wall treatment-soil reconstruction + vegetation greening-interception drainage and water storage " was put forward, and the local section of mine pit 1 in the area was taken as the main test point for application research. After the end of the project, the hidden danger of mine geological disasters was eliminated or reduced, which laid a foundation for better utilization of resources in the area, promoted the ecological restoration of the mining area, increased the income of the people, and produced certain economic benefits.
