Brief Analysis of the Technical Points about the Tailings Pond Environmental Impact Assessment

In recent years, mine tailings dam incidents occur frequently all over China, causing serious loss of life and property as well as posing a serious threat to environmental safety. Tailings pond as the most important part of mineral areas, the environmental impact assessment (EIA) of which is the emphasis and difficulty of mine areas EIA. Relevant authorities of China have paid great attention to the life cycle of tailings pond, environmental impact assessment also calls for special attention. In the view of the fact that separate tailings pond EIA is rare, generally including in the mining and processing project EIA, this paper started from survey and design time, construction period, operation period and closure period over the life cycle of the tailings pond, and then discussed the technical points of the main environmental impact relative to the corresponding period. The environmental protection measures and risk prevention measures were also put forward.
