Study On The Bearing Capacity Of Mine Geological Environment In Panxi Area

Panxi area is an important production area of mineral resources in China.There are abundant mineral resources,complete types of mineral resources and excellent quality in the area.At the same time,the exploitation of mineral resources has also produced a series of environmental problems,resulting in the decline of the geological environmental carrying capacity of mines.Therefore,it is very important to stLudy the bearing capacity of mine geological environment.The study of mine geological environmental carrying capacity can find out the relationship between mining development and geological environmental carrying capacity,systematically summarize the characteristics and connotation of mine geological environmental carrying capacity in Panxi area,grasp the spatial distribution characteristics of high and low areas of mine geological environmental carrying capacity,and provide important reference for promoting the sustainable development of mining industry.Based on the natural environmental impact data,socio-economic impact data,2016 high-resolution remote sensing data,mine development status interpretation data,2016 mining rights data and 30 x30m DEM data in Panxi area,this paper carries out data processing research based on ARCGIS software platform.Based on remote sensing images,information extraction of mine features was carried out,field investigation verification and indoor data correction were carried out.An evaluation index body of mine geological environmental carrying capacity is constructed,which is composed of 18 evaluation indexes such as slope,elevation,vegetation coverage,rainfall,per capita GDP,population density,mineral exploitation planning,mining mode,mining density,mining scale,mining mineral species,exploitation area,geological structure,strata and rock formations,water system erosion,geological hazards,geological hidden dangers and control engineering.In this paper,a multi-index comprehensive evaluation model is used to evaluate the carrying capacity of the mine geological environment in Panxi area,and the zoning map of the carrying capacity of the mine geological environment is drawn.According to the carrying capacity value,the mines in Panxi area are divided into zones of excellent bearing capacity,good bearing capacity,medium bearing capacity and poor bearing capacity.Among them,the area of excellent bearing capacity is 3506.01 km2,accounting for 55.02%of the total area of the study area;the area of good bearing capacity is 14294.59 km2,accounting for 22.44%of the total area of the study area;the area of medium bearing capacity is 10189.77 km2,accounting for 16%of the total area of the study area;and the area of poor bearing capacity is 4164.63 km2,accounting for 6.54%of the total area of the study area.Finally,the reasons are analyzed and the countermeasures and suggestions for the development of mine geological environmental carrying capacity are put forward.Through the research and field verification of the mine geological environmental carrying capacity in Panxi area,the results show that the evaluation results are in good agreement with the actual situation.The evaluation index system and the evaluation model selected are more scientific and reasonable.The research results have important reference for grasping the distribution of the mine geological environmental carrying capacity in Panxi area and judging whether the mining industry and geological environment are coordinated.And its application value.
