Abstract: In order to solve the problem of difficult to cope with the disaster of the multi-hazard coupled mine, the recovery of the working face is difficult. In the multi-research, respect for science on the basis of the relevant experts fully demonstrated, to develop a " Sub-unsealed, one by one lock the wind, nitrogen injection, steady progress " the post-disaster management program to make up for high gas, Impact of multi-hazard coupling work surface accident after the rapid restoration of governance technology gaps. This paper describes the water sealing roadway lock air unsealed, large flow of nitrogen injection, closed area gas pre-pumping, differential pressure on-line monitoring, combined strong support technology and other negative pressure ventilation before the disaster management technology and the total negative pressure ventilation Windshield pressure technology, and a detailed description of the unsealed process for similar mine disaster recovery to provide a successful experience. The results show that the technology can be used to realize the rapid restoration of the disaster-free working face and provide important guarantee for the early safety and restoration of the working face.
