| description | The invention discloses a continuous mining and continuous filling full-negative-pressure ventilation solution. The solution comprises the following steps of roadway construction, coal mining, ventilation, transportation, supporting, filling, monitoring, coal mining on a mining stopping line and workload increase on a working face. Compared with the prior art, the tunnel boring machine has the advantages that the tunnel boring machine performs centralized time operation without idle stroke, time error and centralized production, the yield is increased, after a full-negative-pressure ventilation system is formed, ventilation does not need a local ventilator, full-negative-pressure ventilation safety is achieved, the requirement for ventilation of a stope face in the coal mine safety regulation is met, and mining replaced by excavation and local fan ventilation are strictly prohibited. Coal mining and filling operations are more reasonable and do not affect each other, and situations can be found in time and gr |
