The Hongshaling section of Jiaoqing Highway is located at the junction of Jiefang District and Zhongzhan District of Jiaozuo City.While developing and utilizing mineral resources to promote economic development,it has caused a series of geological environmental problems.In the visible range on both sides of the Jiaoqing Highway,the slag piles formed by mining are randomly stacked,the pits are scattered and the high-steep slopes of the upright slopes have a huge impact on the geology and ecological environment of the Hongshaling section of the Jiaoqing Highway.These geological environmental problems threaten the safety of the Jiaoqing Highway.This paper takes the Hongshaling section of Jiaoqing Highway as the research object,Through on-the-spot investigation and data collation,the geological environmental problems and characteristics caused by mining are analyzed,and the geological environment quality is evaluated,which provides a scientific basis for the supervision and optimization of the geological environment of the mine.(1)Through the collection of data,on-site investigation and data analysis,it is found that the geological environmental problems caused by mining mainly include:land resource compaction and destruction,destruction of topographic and landscape landscapes,geological disasters and specific analysis of the above geological environment problems.(2)From the three aspects of mine geological environment conditions,mine geological disasters and ecological environment problems caused by mining,the evaluation index system was established by using 9 factors,and the analytic hierarchy process was used to compare the relevant factors of each layer by matrix form.The factor assigns the importance of the impact of the geological environment,and finally passes the consistency test to finally obtain the weight value of each factor.(3)The fuzzy comprehensive evaluation method and the comprehensive index method were used to evaluate the impact of the geological environment of the Hongshaling section.The 78 evaluation units of the mine geological environment in this area are divided into three levels:Geological environment affects severe areas,more severe areas,general areas.The area with the most serious impact on the geological environment of the mine is 44,972 m~2,accounting for 5.1%;the area with more serious geological environment impact is 85,847 m~2,accounting for 9.7%.The overall geological environment impact of the study area is moderate.Through the classification and description of the geological environment of the Hongshaling section,the characteristics are analyzed and accurately evaluated,which provides important application value for the appropriate environmental countermeasures for the difference of the grade distribution in the mine environment restoration and sustainable planning.
