多巷布置自燃煤层俯采工作面自然发火原因分析与治理

Analysis and Control of Natural Ignition Reason for the Underhand Stoping Working Face of Multi-roadway Layout Spontaneous Combustion Coal Seam

分析了多巷布置自燃煤层俯采工作面采空区发生煤炭自燃的主要原因,提出了工作面在俯采生产期间自然发火的防治措施,为相似条件回采工作面的火灾防治工作提供了技术依据,积累了实际经验。

This paper analyzed the main reason for spontaneous combustion of coal in the goaf with underhand stoping working face of multi-roadway layout spontaneous combustion coal seam,proposed control measures to spontaneous combustion during the period of underhand stoping,provided technical basis for fire prevention work of the mining working face in similar conditions,accumulated some practical experiences.
