Abstract: In order to solve the problem of insufficient database resources and analysis tools for coal and coalbed methane development, based on the principle of collaborative computing and distributed storage of big data technology, the design scheme of big data platform for coalbed methane is proposed, the big data interconnection mechanism based on cloud technology is established, and the coalbed methane development and utilization model base based on big data mining technology is constructed. According to the system architecture design and function design, a big data platform with Hadoop as the core framework was built, and diversified applications were carried out in government management departments and coal enterprises, providing data basis and decision-making basis for coordinated mining of coal and methane and rational layout of coalbed methane development and utilization.
