基于博弈论组合赋权的矿山地质环境评价

IAiming at the ambiguity and uncertainty of the influencing factors of mine geological environment assessment, taking Muping district mines as an example, from the four aspects of physical geography, basic geology, mine environment and mining development, the index system and classification of mine geological environment assessment were established. Then combined with the game theory idea, analytic hierarchy process (AHP) method, entropy weight method (EWM) and fuzzy comprehensive evaluation method, were established by a comprehensive evaluation model of mine geological environment based on the combination weighting of game theory, and ArcGIS was used to carry out interpolation analysis to obtain the evaluation zone of mine geological environment in the study area.The results show that the overall evaluation of the mine geological environment in the study area is good, but there are some serious mine environmental problems, such as the relatively high weight of the mine geological environment indicators, and the more serious damage to land resources and topographical landscape. The geological environment quality of mines in the study area is divided into 4 minor areas, 12 general areas and 1 severe area. A variety of evaluation methods are used to objectively reflect the current status of the mine geological environment in the study area, and provide a reasonable reference for related protection and governance in the future.
