Theory and method of suitable evaluation for mine environmental positive effects development and utilization

Since the economic reform and opening up, the exploitation of mineral resources has made significant contributions to the economic development of China. However, due to the non-renewable nature of most mineral resources, a considerable number of mines are facing resource depletion and closure. How to develop and utilize the positive environmental effects left by these mines will become a crucial support for extending the mining industry value chain, ensuring green and low-carbon energy development, and achieving China’s strategic goals of “carbon peak” and “carbon neutrality”. To scientifically develop environmentally positive resources in mines, this study focused on four categories of goals in the development and utilization of positive environmental effects in mines: resources, energy, popular science and entertainment, and ecological carbon sinks. Based on the “Supply - Demand - Development” (SDD) constraint combination of mining supply ontology characteristics, specific market demands, and development an
