Application of analytic hierarchy process and fuzzy mathematics comprehensive evaluation in mine geological environment quality evaluation
The development and utilization of mineral resources may bring various environmental problems,and the quality evaluation of mine geological environment is an effective means to evaluate the impact of mining and utilization.Taking a mining area in Qinghai as an example,based on the analytic hierarchy process and fuzzy mathematics method,this study selected 7 index factors,used the analytic hierarchy process to distribute the weights of each element,and then combined with the membership degree matrix calculated by the fuzzy mathematics method,a fuzzy comprehensive evaluation model was built to comprehensively evaluate the quality of the mine geolog-ical environment.The results show that the geological environment quality of the mine in this area is generally good.The evaluation re-sults of this method are basically consistent with the more mature analytic hierarchy process-GIS method,and can achieve accurate eval-uation consistent with the actual situation.
