What Hinders the Promotion of the Green Mining Mode in China? A Game-Theoretical Analysis of Local Government and Metal Mining Companies

Evaluation of Enterprise Green Mine Construction Based on DPSIR Model

As a new mode of mining development, green mine optimizes the development and utilization of mineral resources with a minimum of the environmental impact, and how to objectively evaluate the construction level of the green mine has become the key to promote green mine construction and it has also been an important path to achieve sustainable development of mineral resources. The evaluation system and methods of green mine construction, however, are not perfect at present as the existing green mine evaluation mostly adopts the index scoring accumulation method, with which the internal relations between the indicators are ignored, and the subjective influence it causes is too large. Based on the framework model of driving forces, pressure, state, impact and response, an indicator system is constructed in this paper to express the internal relationship between indicators more intuitively. Combined with subjective and objective combination weighting method to determine the index weight, TOPSIS and coupling coordination degree models are introduced to quantitatively evaluate the spatio-temporal evolution process of green mine construction and the coupling coordination between subsystems, analyze and obtain the main obstacle factors affecting the green mine construction of enterprises, and provide suggestions and countermeasures for the improvement of green mine construction of enterprises. The applicability of the model is verified by an actual case study of a mine in China. The model enriches the connotation of green mines, making the evaluation process and results fairer and more reliable, thus providing an effective way to promote the sustainable development of mines.

Research and development trend of green mining: a bibliometric analysis

As green development has become a mainstream feature of modern development, green technology has become an inevitable trend in the development of mining technology, and related research on the subject continues to accumulate. Based on the bibliometric analysis of the green mining (GM) research from 2001 to 2020, we try to capture GM research and development trends from the perspective of global green development. The results show that the growth rate of GM research is much higher than that of conventional mining research, and the research results are growing rapidly. A visual collaborative network was created to identify the main research countries and author distribution and explore the most contributed journals. The research themes in GM show an evolution from sustainability theory to the application of green technologies in mines to the establishment of long-term mechanisms and policy regulation. The keyword co-occurrence results show that the current GM research covers the whole life cycle of mines. Soil, waste disposal, and recycling are long-standing research hotspots, and the most relevant articles are about resource recycling. Based on the keyword co-occurrence results, the proportion of restoration and management research has rapidly increased from 7.3 to 28.9%. Ecological restoration, reclamation and monitoring, remote sensing, and other technologies are more closely integrated usually accompanied by research related to evaluation and management. With the evolution of the theme, the research on GM is becoming more and more comprehensive. It reflects an extremely strong interdisciplinary and cross-disciplinary character.

An Integrated Gray DEMATEL and ANP Method for Evaluating the Green Mining Performance of Underground Gold Mines

Green mining (GM) can achieve the harmonious development of mineral resource exploitation and environmental protection. Performance evaluation is the key to promoting GM. This research explores favorable methods to evaluate the green mining performance (GMP) of underground gold mines. First, according to the specific characteristics of underground gold mines, an evaluation criteria system for GM is formulated. Meanwhile, the weights are calculated using an integrated gray DEMATEL and ANP technique, which considers the correlation between indicators. Subsequently, the solution methodology for performance evaluation is proposed based on normalization of indicators. Finally, six underground gold mines are utilized as case studies to verify the methodological feasibility. The results of the empirical study show that there is a significant gap between ordinary mines and pilot green mines, and this study, via comparison analysis and cause–effect analysis, gives direction for mines improvement. Not only will the work provide technical and theoretical support for the evaluation and construction of similar green mines, it will also serve as a reference for government policy implementation.
