Research progress on coal resources supply-demand analysis and development-utilization

This paper analyses the global and domestic coal supply-demand under the current situation and looks forward to the development trend of coal mining, coal preparation and coal-bearing series co-associated minerals development and utilization in China. By analyzing of the global and domestic coal supply-demand characteristics, development direction, and then this paper sums up the current situation of coal mining, coal preparation and coal-bearing series coal-associated minerals in China. Based on the main issues faced, proposes development directions in terms of industrial structure, theories, and technological equipment. The results show that in terms of supply and demand, the current global coal production is showing a significant growth trend, of which the Asia-Pacific region accounts for nearly 80%, the global coal consumption has reached a new high, showing a regional differentiation pattern, developing countries have grown significantly, on the contrary, developed economies continue to promote the process of coal withdrawal. The concentration of Chinese coal industry has been further enhanced, and the consumption is in a high shock stage. In the future, China should focus on ensuring the elasticity of supply-demand and solving the contradiction between regional supply-demand. In terms of development and utilization, domestic coal mining and coal preparation industry is facing problems such as unbalanced production capacity structure, insufficient theoretical innovation, dry coal preparation technology unadvanced, and intelligence level should be improved. It is proposed that efforts should be made in industrial structure adjustment, theoretical innovation, technology and equipment research and development, clean and low-carbon utilization, process system upgrading, and intelligent construction. It is necessary to solve the problems of imperfect industrial policy, imperfect top-level design, and unadvanced comprehensive utilization technology of coal measure co-associated mineral resources. This paper suggests to promote the process of comprehensive utilization in terms of building a whole industry chain development system, strengthening basic scientific research, developing refined comprehensive utilization technologies, and improving the management system of mining rights.
