Study On Geological Environment Evaluation Of Daping Iron Mine Area In Yucheng City

Today,with the rapid development of the social economy,environmental issues are getting more and more attention.In particular,the mineral resources,which are the mainstay of the national economy,inevitably destroy the original ecological environment balance in its large-scale mining process,and triggered a series of mine geological environment problems.These geological environmental problems not only affect the working environment and conditions of the mine,but also threaten the lives and property of the residents of the mining area and affect the daily life of the residents.Therefore,in order to coordinate the sustainable development of economy and environment,and thoroughly resolve the contradiction between the exploitation and utilization of mineral resources and geological environment protection,it is very necessary to study the geological environment evaluation of mines.Based on the mining and utilization methods of mineral resources and the field investigation of production technology in Daping Iron Mine Area,Yucheng County,this paper starts from the investigation of the geological environment of the mine in Daping Iron Mine,and combines the geological environment background of the mining area with the distribution of mineral resources.The status quo of the geological environment of the mine,so as to make a comprehensive evaluation of the geological environment of the mine in the Daping Iron Mine.The specific research contents are as follows:(1)Using remote sensing technology and paperless mapping technology,this paper uses traditional geological survey as a technical means to carry out on-the-spot verification of mine geological environment problems,and through qualitative analysis of water and soil samples collected and analyzed by mining areas.Problems in the geological environment of mines in mining areas.(2)The geological problems in the Daping Iron Mine Area determined through investigation mainly include:the occupation and destruction of land resources;the destruction of water resources in the mining area and the pollution of surface water and water environment;the environmental pollution caused by solid waste generated;The geological disasters caused;the extent and status of the mined areas in the mining area.Through statistical analysis of field survey data,combined with the basic geological data of the mining area,the status quo of mine geological environment problems is analyzed.(3)For the geological environment of mines,firstly use the analytic hierarchy process to select the evaluation factors scientifically,reasonably and objectively,and establish the evaluation index system.Secondly,use the GIS platform for single factor evaluation,and use the relevant technical specifications and standards to conduct single factor.The scores are graded,and then the comprehensive index method and the fuzzy comprehensive evaluation method are used for comprehensive evaluation.Finally,the evaluation results obtained by the two evaluation methods are analyzed to achieve the purpose of reasonable evaluation of the mine geological environment and corresponding prevention measures are proposed.(4)By analyzing the two evaluation results,combined with the comprehensive evaluation of the partition map,it can be found that the geological environment of the mine is damaged by the influence of human production activities.Among them,the geological environment problems caused by mine production are diversified and more serious.The areas where mine production activities are not restored and ecologically restored are all areas with poor geological environment,with an area of about 22km~2,accounting for 34.38%of the study area;the middle area of the mine geological environment is a lighter area affected by mine production and The area that has been restored to governance has an area of about37km~2,accounting for 57.81%of the study area.The urban villages where residents live and the areas far from the mines have a good geological environment,with an area of about 5km~2,accounting for 7.81%of the study area.
