In order to effectively control and monitor the gas information of the 22109 working face, the gas information management system was specifically applied to the 22109 working face by specifically analyzing the design purpose, process and gas point parameter point-by-point prediction function of the gas management information system. The gas content was analyzed and predicted by various functions in the system. The results showed that the 22109 working face used the gas management information system to clearly and intuitively display the gas distribution status of the working face, and could predict the gas content of the working face, with better guidance for gas management work at the working surface.
