Abstract: Under the condition that the traditional gas management model of Zibo Mining Group has been unable to adapt to the requirements for effective gas management and control, through strengthening gas management, promoting the implementation of gas drainage projects, and preventing and controlling well in advance, the early warning mechanism of the three-level gas management was established. The results show that: the number of gas overrun alarms from Tingnan Coal Mine changed from more than 500 times a year, with the gas concentration in the return air flow sometimes reaching more than 1.5%, to zero, the effect is significant; the effective production time of the working face is increased, ensuring that the annual output of coal reaches more than 4 million tons, the economic benefits are obvious; the gas hazard is basically eliminated, which improves the safety of workers on the job site.
