Evaluation and empirical research on green mine construction in coal industry based on the AHP-SPA model

Abstract

Green mine construction plays a crucial role in achieving sustainable development in the coal industry and promoting a low-carbon economy. However, evaluating the universal applicability of green mine construction standards and their effects remains a significant challenge. To address this issue, we propose an innovative approach by developing a comprehensive green mine evaluation index system based on eight dimensions: standardized management, technological innovation, environmental protection, land reclamation, community harmony, enterprise culture, comprehensive utilization, and energy saving and emission reduction. To evaluate green mine construction, we combine the analytic hierarchy process and set-pair analysis to provide a more accurate and comprehensive assessment. Our study provides new insights into the sustainability of coal mining operations. Firstly, we identify regional imbalances in green mine construction, with the eastern region leading in green mine construction, followed by the central and western regions, while the northeast region lags behind. Secondly, we find significant differences in the level of green mine construction among coal enterprises, with large coal enterprises showing higher levels of green mine construction due to their greater capital investment and advanced technology. Moreover, our study highlights the importance of technological innovation in green mine construction and its positive impact on promoting sustainable development. Our approach offers innovative methods for improving the evaluation of green mine construction and promoting sustainability in the coal industry, making it a valuable contribution to the field.
