Study On Renovation And Regeneration Design Of Abandoned Limestone Mine In Dalian

With the rapid development of social productivity,the demand for mineral resources on Earth by human society is increasing day by day.At the same time,the mines left behind by the large-scale mining of mineral resources are gradually idle or even abandoned due to the difficulty of restoration technology and high construction costs.With the further acceleration of the process of the national ecological sustainable strategic development and the gradual improvement of the ecological restoration system,the mining area after the depletion of mineral resource depletion may not be the burden of the Urban ecosystem.If it can be successfully transformed and regenerated through ecological restoration technology,it will often become a new help to enhance the competitiveness of cities.Therefore,this article takes the abandoned limestone mines of Anshan Mining Company of Ansteel Group in Dalian as the research object,aiming to improve the utilization rate of land resources in Dalian,promote the development of tourism projects in the construction of ecological vacation demonstration areas in Ganjingzi District,Dalian,and use modern restoration theory and technology to guide the reuse of abandoned limestone mines in Dalian.Suggestions for renovation planning and design are proposed.Based on the design goal of repairing and reusing limestone mines in Dalian,this article first elaborates on the concept,policies and regulations related to abandoned industrial sites.Based on excellent practical cases at home and abroad,it analyzes the treatment methods for the reuse design of abandoned mines at home and abroad,summarizes experiences and lessons learned,and proposes core design ideas suitable for this research object,And based on this,explore the relevant technical methods and transformation development models for ecological restoration in mining areas,providing technical support and design basis for the later planning and design of Dalian limestone mines.Further exploration and analysis of the existing basic conditions of the Dalian limestone mine pit were conducted through preliminary on-site research,comprehensively discussing the potential value and renovation risks of the mining area.Summarize the many problems currently existing in the mining area,propose targeted transformation strategies,reasonably use reuse strategies and methods,reshape the ecological characteristics and atmosphere of Dalian limestone mines,restore the land use function,and achieve waste reuse at the spatial and cultural levels.Based on the theoretical results of the research,the feasibility of achieving the goals is tested,and a detailed overall planning and design is carried out for the abandoned limestone mine in Dalian.Finally,a summary and outlook on the current research status of the reuse of abandoned industrial sites in China are proposed.The results of this study have certain guiding and practical significance for improving the land resource utilization rate and the ecological environment of mining areas in Dalian.
