Abstract: For the characteristics that close coal seam fire area is easily affected by mining, and air leakage between the layers will speed up reburn of fire area, from the perspective of strong support, air leakage control, advanced prediction, active prevention and control, a complete set of monitoring, prevention and treatment system for spontaneous combustion prevention and control is established for the lower seam during the tunneling period. Practice shows that strengthening roadway support, whole section shotcrete, constructing observation drilling, nitrogen injection and other measures can effectively reduce the threaten of overburden fire area on the safety driving of the mining seam on the basis of reducing fire zone disturbance.
