摘　　要：随着矿井服务年限的增加,采掘过程中遗留旧巷数量也不断增加,由于通风系统的调整、矿山压力造成的煤的透气性增强以及大量的遗煤等原因,在旧巷易产生高温火点,进而形成火灾。通过分析旧巷高温火点产生的原因,结合影响高温火点产生因素,提出了合理布置、安排采掘计划,同时采取注浆、喷浆、调整通风系统等综合预防火灾措施。With the increase of mine service life, the residual coal in old roadway is increasing in mining process. Because of the ad- justment 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.
