Geological Environmental Impact Assessment Of Mines In Yinkeng Mining Area In South Of Jangxi Province

In the development of society,the development and use of mineral resources has played an indispensable role.However,the development and utilization of mines bring great benefits,while causing damage to the natural world,and thus causing various geological disasters,water and soil pollution and other issues.The Yinkeng mining area in Yudu County,Jiangxi Province is rich in mineral resources,diverse in species,and relatively concentrated in the distribution of minerals.Due to economic and technological factors,the recovery and control of mining environment is lagging behind.The remote sensing technology combined with ground investigation is used to evaluate the impact of mine geological environment.It is conducive to the planning,improvement and treatment of the future geological environment of the mine.Based on the evaluation of the geological environment impact of the mine on a single mine,this paper divides the geological environment impact of the mine in the area,and concludes that the geological environment of the mine in the study area has serious,serious,light and extremely light regional division.The work is as follows:(1)Collect various materials such as geological,environmental and disasters in the study area and conduct remote sensing and field surveys on the area to obtain objective data of the mine geological environment in the area.In the process of remote sensing survey data processing,the data fusion process of Superview-1 was deeply studied.Combined with remote sensing survey,field survey and soil and water sample collection and analysis,the geological environment problems of the mine are identified as geological disasters,topography,land destruction and soil and water pollution,and detailed description and analysis are carried out.(2)Selecting 11 evaluation indicators of three element layers of single mine development and single mine geological environment to establish a single mine geological environmental impact assessment index system suitable for the region,and quantify the evaluation indicators,using comprehensive evaluation method as The evaluation model was used to evaluate the impact degree of single mine geological environment in the study area.(3)Based on the results of geological environment impacts of single mines,using the interpolation analysis of arcgis,the research is divided into four areas: severely affected areas,more severely affected areas,slightly affected areas,and weakly affected areas,and the mine geology is caused by the mining area.The reasons for the more serious environment were analyzed and reasonable suggestions were put forward.The evaluation results of this paper provide a scientific basis for mine geological protection and restoration management in Yinkeng Mining Area,Yudu County.
