Abstract: With the increase of mine service life, the residual coal in old roadway is increasing in mining process. Because of the adjustment of ventilation system, the enhanced permeability of coal caused by ground pressure and a lot of residual coal, it is prone to produce high-temperature fire point and fire hazard in old roadway. This article analyzed the reason of high-temperature fire point in old roadway, introduced reasonable arrangement and mining plan combined with factors of high-temperature ignition point. At the same time, we take comprehensive measures including grouting, spraying, adjusting the ventilation system to prevent fires.
