Abstract Based on the possibility of summer mine roof convergence, water inflow increasing leaded to localized tunnel collapse, ventilation system interruption risks, the thesis proposed the formation of the temporary use of the main auxiliary shaft into the return air system, long-distance air supply solutions, combining mine ventilation conditions and situation. The rational use of the main mine roadway system and the auxiliary shaft for the wind conditions successfully completed the ventilation during disaster relief missions, provided an effective way for the use of the main auxiliary shaft mine ventilation system and remote temporary local exhaust ventilation for relief.
