Abstract: In view of the isolation of the coordinated development and production system of coal and coalbed methane, the complexity of continuous design and the poor scientificity of traditional manual compilation, The definition methods of various process types such as surface drilling and extraction of coalbed methane, well construction and development, roadway preparation, coal mining in working face and underground drilling and extraction of coalbed methane throughout are studied. The spatial layout relation and time connection relation database are constructed. The intelligent design platform of production system is developed by using engineering queuing method, dynamic programming method and critical route method. While the process database is built, the construction progress bar chart is generated synchronously, which is convenient for engineers and technicians to check the mutual constraint relationship between various engineering tasks at any time. The project progress report is generated synchronously, and the dynamic statistical analysis of the report per unit production and single entry is realized. At the same time, it also integrates dynamic monitoring functions, including construction team monitoring, connection relationship monitoring, spatial relationship monitoring and key route monitoring. When time conflict, space conflict, connection relaxation, connection tension, construction idle, construction interleaving and other conflicts occur between tasks, the system will automatically alarm and , so as to provide quantitative data support for engineers and technicians to modify the connection system. The results show that the system innovatively expands the single isolated and static production system into a fully integrated and dynamic production system of the four systems of "pumping, construction, excavation and mining" of the whole mine. It can realize the systematic, digital and fine connection of coal and coalbed methane development, realizing the rational layout of coal and coalbed methane development space and orderly connection in time, help the integrated and coordinated development and production practice of coal and coalbed methane, and improve the informatization and intelligence level of mine production.
