Research On The Combination Evaluation Model Of Mine Geological Environment Based On Grey Correlation Degree, AHP And Fuzzy

Mineral resources are the important material basis for the development of our socialeconomy.With the steady growth of population in our country, the rapid development ofnational economy, demand for mineral resources has increased dramatically, There are a seriesof mining-induced environmental problems due to the large-scale, high intensity of miningresources activities, The mine geological environment problems not only threatens our livesand our property safety, but also affects and restricts the economic developmentseriously,and caused a series of social problems and contradictions. So, it has importanttheoretical significance and practical value to establish a scientific and reasonablecomprehensive evaluation index system of mine geological environment, choose an idealevaluation model of comprehensive evaluation of mine geological environment and providesthe government and enterpriseswith a scientific basis of proper use of mineral resources.This article set out from the numerous factors influencing the mine geologicalenvironment problems, they are divided the mine geological background, the mininggeological environment current situation and the mining of natural geographical environmentthree parts, selected11factors as evaluation factors evaluation system in the numerous factors,established a multi-level evaluation index system of mine geological environment.Established a combination evaluation model based on grey relation analysis, analytichierarchy process comprehensive evaluation model and fuzzy comprehensive evaluationmodel combined, to analyze different fuzzy synthesis operator selection, completed thereliability of the model analysis, and by using C++language programming, to complete theimplementation of the combination evaluation model. Finally in this paper, used thecombination evaluation model to evaluate the quality of Mine geological environment basedon the a’xi gold mine geological environment data from Sichuan province, the evaluationresult is same as the evaluation result that mine bureau of sichuan province northwestgeological team has gived, so the reliability of the system has be verified.The comprehensive evaluation of mine geological environment problem shows that thea’xi gold mine geological environment is good, by analyzing the a’xi mine geologicalenvironment current situation, to analyze the potential geological disaster in mine mining later,and to analyze the possibility and degree of the geological disaster, and put forward thesuggestions for the mine geological environment protection and prevention measures.
