Abstract
Mine geological environment evaluation is an important measure to realize the reasonable exploitation and utilization of mineral resources and environmental protection.This paper studied the mine geological environment characteristics and the main mine geological environment problems in geological environment problem area of Kunyang phosphate rock systematically based on the high score 2 remote sensing image data,and determined the evaluation index system of mine geological environment according to it,using AHP decision analysis method determined the weight of the evaluation index,and evaluating the mine geological environment of the study area based on ArcGIS technology platform.According to the evaluation results:the mine geological environment is divided into mine geological environment serious area,more serious area,general area and no impact area.The results show that the quality of the geological environment in the study area is generally good.The research results have important reference value for guiding the sustainable development and utilization of mineral resources in the area of geological environment of Kunyang phosphate rock.
