Research on the Evaluation Model and Suggestions of Coal Resources Mining Level in China

As the basic energy resource of China, coal is a reliable energy supply provided for the national economy and social development. But with the adjustment of economy and energy structure, the coal industry now is facing some prominent issues such as overcapacity, low production efficiency, high pressure of production safety and environmental protection. According to the characteristics of coal industry, the evaluation model and indicators system of coal mining level based on four dimensions of production safety, production efficiency, resource recovery and environmental protection were established, and the weight of each indicator was determined. Considering the indicator values of America's coal industry to be the standard, coal mining level of China, America, Australia and the Inner Mongolia Autonomous Region of China were evaluated and analysed comparatively. Based on the analysis of the development environment of China's coal industry under the new situation, five suggestions for improving the level of coal resources exploitation and promoting the green and sustainable development of China coal industry were put forward.
