4302工作面采空区自燃发火条件及应对措施分析

为防止煤矿井下采空区自燃发火,针对4302工作面的实际环境,分析了工作面采空区煤体氧化情况及应对措施,并对U型和Y型通风条件下采空区自燃三带的形成原因以及Y形通风工作面防灭火措施进行了分析,为今后预防矿井工作面采空区自燃发火提供了科学依据和有力保障.

Conditions and Countermeasures of Spontaneous Combustion in Goaf on No.4302 Working Face

To prevent spontaneous combustion in goaf,the coal oxidation in goaf and countermeasures were analyzed based on the actual environment of No.4302 working face.In addition,this paper analyzed the formation of the three zones of the spontaneous combustion in goaf under the U-shaped and Y-shaped ventilation,as well as the fire prevention measures under the Y-shaped ventilation,which could provide a scientific basis for the spontaneous combustion prevention in the future.
