Abstract: The coal industry is the basic industry to ensure the safe and stable supply of energy in China. The continuous innovation and iteration of technology and equipment for the development and utilization of coal resources and the construction of intelligent super coal mine are important measures to develop advanced productivity in the coal field and help the high-quality development of the coal industry. The development of surrounding rock control technology in stope in China in recent years is systematically described, the evolution law of mining stress and the process of surrounding rock fracture and instability are analyzed, and the mechanical model of surrounding rock fracture and instability, control criteria and reasonable working resistance calculation method of hydraulic support are innovated. The development process of fully mechanized mining technology and equipment in China is elaborated, and the complete sets of equipment with the maximum mining height of 10m and the maximum supporting height of 7.0m are developed, which solves the technical problems of safe and efficient mining of shallow buried deep, hard, thick and extra-thick coal seams in western mining areas. This paper systematically analyzes the status quo, key technologies, achievements and main problems of intelligent coal mine construction in major coal producing areas of China, proposes the definition, characteristics and connotation of intelligent super coal mine, and expounds the achievements and experience of typical super coal mine construction. And from the standard system, data system, technology system, management system, ecological system construction and other aspects of the future development direction of the coal industry, to help the coal industry to achieve high-quality development.
