摘　　要：为了更好为类似矿山弃渣场生态修复工程提供参考,通过运用实地调查和综合研究等方法,对矿山弃渣场堆渣特征和生态环境问题进行分析研究,同时采用定性和包括三维有限元在内的两种定量分析方法,对堆渣边坡进行综合稳定性分析,并提出生态修复对策。研究结果表明,矿山弃渣场生态环境问题主要有:地质灾害隐患、地貌景观及土地资源破坏、水土流失和视觉污染;弃渣场边坡处于基本稳定状态,坡体中上部表面存在局部失稳危险;通过坡面整治、坡面防护、覆土绿化和截排水等工程手段,实现对矿山弃渣场的生态修复。In order to better provide a reference for the ecological restoration project of similar mine slag dumps,the characteristics and ecological environment problems of the slag dumps in the mine slag dumps were analyzed and studied by using field investigation and comprehensive research,and two quantitative analysis methods,including qualitative and three-dimensional finite elements,were used to comprehensively analyze the stability of the slag slope and put forward ecological restoration countermeasures.The results show that the ecological and environmental problems of mine waste disposal site mainly include:geological hazards,destruction of landform landscape and land resources,soil erosion and visual pollution.The slope of the slag dump is in a basically stable state,and there is a danger of local instability on the middle and upper surface of the slope.Through slope remediation,slope protection,soil covering and greening,interception and drainage and other engineering means,the ecological restoration of the mine slag site is realized.
