The mining industry provides an important material basis for modernization and has become the basic industry for China’s economic construction.In order to promote the high-quality development of mining industry，the construction of green mines is the only way for sustainable development.There are studies on the evaluation of green mine construction，which mainly focus on the content analysis method and case study method，but rarely from the perspective of policy design，while the government is also an important subject to promote green mine construction.In order to improve the adaptability and scientificity of the policies，it is necessary to conduct a systematic evaluation of China’s green mine construction policies.Therefore，this study quantitatively evaluated and assessed the existing green mine construction policies in China，identified the deviations and shortcomings of the existing policies and proposed optimization strategies，which is of great theoretical and practical significance for the development and improvement of green mine policies in the new era.Unlike subjective evaluation methods such as expert scoring，the study analyzed the content of 193 green mine construction policies in China between 2005 and 2021 through social network analysis and text mining，extracted important subject terms，and build a framework for evaluating green mine construction policies on this basis.39 of these policies were selected as samples （13 policies at the central level and 26 policies at the local level）.The Policy Consistency Index Model （PMC），an important modeling method for policy research analysis，was used for quantitative evaluation and comparative analysis.The study found that China’s green mine construction policies are reasonable，but there are still some problems that need to be improved.Among the 39 selected Chinese green mine construction policy texts，8 of them are excellent，31 are acceptable，and there are no perfect and poor policies，while the central government’s policies generally score higher than local governments.At the central and local levels，there are common problems in green mine construction，including the scope of regulation and implementation agencies are small，economic benefits，tourism aspects，long-term planning，talent incentives，laws and regulations need to be improved.At the regional level，there are differences in green mine construction policies，including the lack of effective supervision in the central region，the lack of binding in the northeast region，and the need to improve the policy areas in the eastern and western regions.The research results provide a reference basis for the formulation of green mine related policies in China，and also provide new ideas and methods for the evaluation of green mine construction policies.
