Research On Geological Environment Protection And Restoration Treatment Plan Of Hongtai Iron Integration Area

The large-scale development and utilization of mineral resources has enabled human beings to enjoy the benefits of natural resources,as well as a series of bitter fruits such as environmental pollution,resource destruction and ecological deterioration,especially in some local mining areas with large-scale predatory mining.It is causing serious geological disasters and geological environmental problems.Therefore,it is extremely urgent to study the prevention and control of geological disasters and the restoration of geological environment.Through the investigation of the mine geology of the Hongtai iron ore integration area,the current situation of the geological environment of the mine and the geological environment problems brought by the future mining are analyzed,and the solution is proposed in a targeted manner.According to the geological environment assessment,the geological hazard type in the mine is the mining subsidence,which is dangerous;the mining activity has less damage to the aquifer;the open pit of the mine,the open pit of the goaf,the landform of the dumping site and the destruction of the landscape The degree of impact is serious,and the topography and landscape of the mining industry site are seriously damaged and affected.The other areas of the mine have less damage to the topography and landscape.The results of prediction and evaluation indicate that the underground mining causes the risk of geological disasters caused by coal mining and collapse;the degree of aquifer damage is serious;the mining open pit,underground stope and rock movement range have serious damage and influence on the topographical landscape,mining The open pits,dumping sites and industrial sites of the empty area control have serious damage and influence on the topography and landscape.The other areas of the mine have less damage to the topography and landscape,and the degree of damage and damage to the land resources of the mine is serious.The comprehensive evaluation and evaluation results show that the impact of mining activities on the geological environment is serious,and it is necessary to focus on the geological disasters caused by the mining subsidence and the land resources problems such as landforms and land occupation.The Hongtai iron ore integration area is divided into key prevention areas(A)and general prevention areas(B).Among them,the key prevention areas include open pits,underground mining rock movement range,goaf control pits,dumps,and industry.Sites;other areas are general control zones,and geological environment control projects are proposed for production control periods and closed pit recovery periods.Figure23;Table17;Reference 51...
