摘要
寒旱草原区的露天矿在开展地质环境保护与土地复垦工作时常面临地质环境复杂、自然环境恶劣等诸多困难,为了解决这类地区露天矿缺乏较为理想的修复方案的难题,以胜利西二矿为例,分析了露天矿地质环境与土地损毁现状及瓶颈问题,针对性提出优化方案。通过增施有机粪肥、保水剂、微生物菌剂恢复土壤功能,选择抗逆性强的草本及灌木进行土地复垦,以不同生活型植物进行植物配置,使植物种类形成优势互补,提高复垦效果。采用优化措施后,寒旱草原区的露天矿取得了更好的地质环境保护与土地复垦效果。
The open-pit mine of cold and arid grassland area often faces many difficulties in carrying out geological environment protection and land reclamation,such as complex geological environment and harsh natural environment.In order to solve the problem that the open-pit mine in this kind of area is lack of ideal restoration scheme,this article takes Shengli West No.2 Mine as an example,analyzes geological environment,land damage status and bottleneck problems of the mine,and puts forward the optimization scheme.By applying organic manure,water retaining agents,and microbial agents to restore soil function,selecting herbs and shrubs with strong stress resistance for land reclamation,configuring plants with different life forms to form complementary advantages of plant species,the reclamation effect can be improved.After using the optimized measures,the openpit mines achieve better geological environment protection and land reclamation effects in cold and arid grassland areas.
