Research on Evaluation of Mine Geological Environment and Restoration

Constructing a scientific evaluation system of geological environment and restoration can provide a reliable theoretical basis for mine geological environment protection. In this paper, we firstly constructed the evaluation system of 10 indicators and 30 sub-indicators as the index of ecological environment and restoration. The hierarchical analysis method was used to evaluate each mine according to the actual situation in Chongqing. We took Mengte mine as a study area and obtained the parameters of soil, water, vegetation, and biology by field experiment. Analytic hierarchy process was applied to this paper and the weight of each indicator was calculated based on expert scoring method and the experience method. This research provided technical support for geological environmental assessment in other mines.
