Abstract: A major breakthrough has been made in exploration of deep coalbed methane (CBM) in recent years, leading the CBM industry to enter its best period in history. However, the rapid expansion of the industrial scale still faces many problems and challenges. To promote the comprehensive upgrade of deep CBM exploration and development, implement the development strategies for large-scale CBM industry, guarantee energy security, and achieve the "dual carbon" target, a systematic analysis was conducted on the current status, theoretical and technical progress, industry upgrading strategy, and challenges in the deep CBM industry. The study suggests that the connotation of upgrading the deep CBM industry can be summarized in four aspects, i.e., theoretical and technical maturity, improved development efficiency, strong investor confidence, and rapid scale expansion. The basic conditions for industry upgrading include six aspects, i.e., policy support and guidance, technological innovation and breakthroughs, infrastructure construction and improvement, talent training and introduction, coordinated development of industrial chains, safe production and environmental protection. For deep CBM industry upgrading, the study proposes a "Eight-in-One" technological, economic, and management system integrating exploration and development, geology and engineering, theories and technologies, underground and ground surface, research and production, investment and profitability, big data and artificial intelligence, as well as strategy and tactics. By integrating exploration and development with geology and engineering, it is feasible to achieve an integration of theoretical research and technological innovation, promote the rapid transformation of scientific research achievements and their applications in production, improve the whole technological level, and enhance technological innovative ability. Through the integration of underground and ground surface development, the coordinated development of underground resources and ground facilities can be achieved to ensure safety operation and environmental protection throughout the entire process. By integrating investment efficiency, big data and artificial intelligence, resource allocation can be optimized and development costs are reduced. Through practical applications, the CBM exploration and development efficiency has been significantly improved; an operation mechanism has been formed through government organization under the leadship of enterprises. A set of coordinated and mutually supporting strategic development goals and corresponding strategies have been formulated and implemented, achieving remarkable effects. To achieve the goal of deep CBM industrial upgrading in the future, it is required to strengthen five aspects and implement three programs, i.e., to strengthen the technological innovation and R & D investment, cooperation and coordination between upstream and downstream of the industrial chain, safety and environmental protection management, international cooperation and exchange, as well as policy support and guidance; adhering to the implementation of "technological innovation as the main body, resource, technology, talent, policy and investment as a whole, as well as coordinated and innovative development" in a coordinated and cooperative manner, to effectively implement the "deep coal seam gas revolution" project, gradually implement the "Eight-in-One" strategic system, and promote industrial upgrading and development.
