Abstract: Based on the current situation of the development of intelligent coal mines in China, the overall technical architecture of intelligent coal mine construction of 'one cloud + one converged network + three-level platform + N application modules' is proposed. The study analyzes the idea of building an intelligent integrated control platform based on micro-service architecture. The idea is to construct the intelligent coal mine platform of unified procurement, unified construction and integrated operation and maintenance model with unified technical architecture, functional modules increasing or decreasing and varied hardware parameters. This paper systematically analyzes ten pain points in the development of intelligent coal mines in China, including unified understanding and concepts, unbalanced development of intelligent mines, immature 5G application scenarios, insufficient technical support for 'transparent geology', unbalanced development and extraction and unbalanced extraction and support, poor adaptability to complex conditions, difficulties in compatibility and coordination of intelligent giant systems, immature development of intelligent robots above and below mines, insufficient management and talent reserves and insufficient investment guarantee. From the aspects of theoretical innovation, technological innovation, equipment innovation, management model innovation and talent system innovation, this study points out the direction of scientific and technological research that needs to be carried out for the intelligent construction of coal mines in China, and proposes the development direction and measures for building a new system of intelligent and green coal industry.
