摘　　要：纳日贡玛矿区位于唐古拉山脉东段,地质构造复杂多样,由于矿山勘查引发地质环境问题,主要表现为钻探、槽探、修筑简易道路对土地资源的破坏、地形地貌景观的破坏、含水层的破坏等。结合区内原始地貌条件、水文地质条件及植被地质环境,对项目区拟采取矿山道路治理工程、探槽治理工程、钻井平台治理工程等分项工程综合治理,实现与周边自然地貌景观基本协调一致的目的,总计需治理面积183100 m~2。通过地貌景观修整工程措施、人工种草技术,重建了矿区地质环境,改善了当地脆弱的地质环境,减少了水土流失量,使牧草地的生态功能得到恢复,增强了当地畜牧业发展后劲,促进了地区经济和社会的可持续发展,具有很好的环境和社会效益。Narigunma mining area is located in the eastern section of Tanggula Mountains,and its geological structure is complex and diverse.Geological environment problems caused by mine exploration are mainly manifested as the destruction of land resources,the destruction of landform and geomorphic landscape and the destruction of aquifer,which is resulted by drilling,trough exploration and construction of simple roads.Combined with the original geomorphic conditions,hydrogeological conditions and vegetation geological environment in the area,the project area plans to adopt the comprehensive management of sub-projects such as mine road management project,exploration channel management project and drilling platform management project,so as to achieve the purpose of basically harmonizing with the surrounding natural geomorphic landscape,with a total area of 183 100 m~2 to be controlled.Through the landscape repair engineering measures and the technique of artificial grass,which is to rebuild the mine geological environment,to improve the local fragile geological environment,to reduce the soil loss,to make the ecological function of the grassland restoration,to sustain the local animal husbandry development and promote the regional economic and social sustainable development.It has very good environmental and social benefits.
