摘要
综放工作面及采空区内遗煤自然发火问题一直是影响矿通防安全的重大隐患。在第一时间掌握采空区内甲烷、一氧化碳、乙烯、乙炔等气体的浓度,对了解采区内的气体环境组成,预防煤炭的自然发火,具有重要意义。
The problem of spontaneous combustion of leftover coal in fully mechanized caving face and goaf has always been a major hidden danger affecting the safety of mine ventilation and prevention.To grasp the concentration of methane,carbon monoxide,ethylene,acetylene and other gases in the goaf at the first time is of great significance for understanding the composition of the gas environment in the mining area and preventing the spontaneous combustion of coal.
