Research on Constructing Mine Geological Environment Evaluation Model Based on the Weights of Evidence
The evaluation of mine geological environment is a major basis and important research content of implementation of supervision and control planning of the mine geological environment. However, there are some limitations to the existing evaluation methods. With the rare earth mine in southern Jiangxi as the research area, the influencing factor of mine geological environment as the evidence layer based on the weights of evidence, and historical distribution point of geological disaster as the training sample points, this paper constructs an evaluation model, and determines the sequence of impact of the evidence layer on the quality of geological environment in the research area through qualitative and quantitative analysis, and also obtains the following conclusion: there is a difference between the impact of different evidence layers and different ranges of the same evidence layer on the mine geological environment.
