Study On Geological Environment Impact Assessment Of Quluo Mining Quartz Open-Pit Mine In Zhouzhi County,Qinling Mountains

After more than ten years of mining and utilization,the mines in the Qinling area have played an important role in promoting the rapid development of China's national economy.However,due to the lack of awareness of environmental protection during the mining process,the development of a large number of mineral resources has caused many ecological problems.In order to restore and control the geological environment of the Qinling area,we need to investigate and analyze the geological environment conditions of the mine through investigation and analysis,According to the problems faced by the mine,select the appropriate assessment method to evaluate the geological environment of the mine,According to the evaluation results of the geological environment of the mine,the treatment plan suitable for the geological environment is given.This paper takes the Luoyu quartz mine in the Qinling area of Zhouzhi County as the research object,and investigates the geological background of the mine through investigation and research,and analyzes the impact of the development of the mine on the land resources and topography,The type and scale of geological disasters in the mine and the possible losses and potential hazards are investigated and analyzed.According to the "Code for the preparation of mine geological environment protection and governance restoration plan",select the appropriate evaluation index,And determine the weight of each evaluation index by means of Analytic Hierarchy Process(AHP);The mine was evaluated by the gray comprehensive evaluation method,the fuzzy comprehensive evaluation method and the comprehensive index evaluation method.Comparing the evaluation process and the evaluation results of the three assessment methods through majority decision making.By the complexity and accuracy of the assessment process of comparing the results of evaluation,to select the most suitable method for evaluation of the mine,There are a large number of open pit mines in the Qinling area of Zhouzhi County.The scale of mining is relatively small,the geological environment is similar,and the geological environment problems of the mine are basically the same.The results of this paper are applicable to the geological environment assessment subarea of the mines in the region.Correct and reasonable evaluation of the zoning results plays an important role in the governance of the geological environment of the mining area.Through the zoning,it can be known that the geological environment in the mining area has received serious impacts,and the ecological and environmental problems facing the area are targeted.Governance,in order to restore the geological environment of the mine,so that the ecological environment of the mine can be restored as much as possible before the mining.
