摘要
作业面的长回撤周期,使得采空区遗煤长时间同空气接触氧化,存在较大的自燃风险。针对此,结合具体工程实际,在进行采空区遗煤自燃防灭火分析的基础上,设计了具有针对性的综合防灭火方案,并对其实际应用效果做出分析。结果表明,综合防灭火方案实现了对火灾隐患的有效控制,确保了长周期回撤作业的安全性。
The long retracement period of the working face makes the coal in the goaf long-term contact with air for oxidation,which has a large risk of spontaneous combustion.In view of this,combined with the actual engineering practice,based on the analysis of fire prevention of spontaneous combustion of residual coal in goaf,this paper designed a targeted comprehensive fire prevention program and analyzed its practical application effect.The results show that the integrated fire prevention program achieves effective control of fire hazards and ensures the safety of long-term retracement operations.
