ABSTRACT

There are increasing number of abandoned mines, which has gradually become a striking challenge for sustainable development and resource recycling. Safety risks and environmental pressures have obliged the mining industry to achieve the secondary development of mines. This paper builds a conceptual framework for abandoned mine resource utilization, and then denotes the 5 R principles (remining, recovery, redevelopment, reutilization, and recycling) and the energy-based, resource-based and function-based development patterns for scientific resource deployment with abandoned mines. Decision factors are investigated from four types of reutilization modes with 43 indicators, which can be classified as economy, resource potential, geography and safety. An integrated analytic hierarchy process (ANP) and strengths, weaknesses, opportunities, threats (SWOT) model are employed to explore the suitable reutilization methods for abandoned mines. The results from the case study show that suitable temperature conditions and technical problems are the top two decisive factors with weights of 0.3178 and 0.1604 respectively. The best strategy for a stone pit is to develop the service industry, which is valued at 20.99% in the seven strategies. The findings of this research indicate the urgent task of abandoned mine database construction and the significance of social performance management for mine closure. Implications are advanced for sustainable management and abandoned mine resource conservation, which help to implement low-carbon transition in the mining sector from the life cycle and cradle-to-cradle perspectives while achieving socioeconomic development and the transformation of resource-based cities.

摘要

废弃矿山越来越多，逐渐成为可持续发展和资源回收利用的突出挑战。安全风险和环境压力迫使矿业实现矿山二次开发。本文构建了废弃矿山资源化利用的概念框架，进而提出了5R原则（再开采、回收、再开发、再利用、循环利用）和能源型、资源型、功能型的发展模式，以实现资源的科学配置。与废弃的矿山。从经济性、资源潜力、地域性和安全性43个指标4类再利用模式中考察决策因素。综合层次分析法 (ANP) 和优势、劣势、机会、威胁（SWOT）模型被用来探索合适的废弃矿山再利用方法。案例研究结果表明，适宜的温度条件和技术问题是前两个决定因素，权重分别为0.3178和0.1604。石坑最好的战略是发展服务业，在七大战略中的估值为20.99%。本研究结果表明废弃矿山数据库建设的紧迫任务和社会绩效管理对矿山关闭的意义。对可持续管理和废弃矿山资源保护具有重要意义，
