Abstract: Combined with the previous experience of fire preventing and extinguihing technology of 1305 fully mechanized caving face in Guojiahe Coal Mine, and starting from the technological aspects, we improve the arrangement of inlet and return airway at 1305 working face to avoid the broken coal oxidation and spontaneous combustion problem above the tail boom of support and reduce the amount of residual coal in the gob. By comparing prevention and control data of 1303 working face during support withdrawing, it reflects the superiority of fire prevention and extinguishing measures at 1305 working face and makes 1305 working face support withdrawing more safe.
