豹子沟煤矿采空区自燃“三带”分布规律研究

Distribution Law of "Three Zones" of Spontaneous Combustion in Goaf of Baozigou Coal Mine

采空区遗煤自燃的防治,需要对采空区自燃"三带"分布规律进行研究。本文针对豹子沟煤矿综放工作面自燃"三带"分布问题,科学合理设计监测方案,从氧气浓度监测、温度变化和CO浓度变化角度进行研究,根据氧气浓度监测结果与温度变化监测结果比较,得到10101工作面"三带"分布规律,为采空区自然发火防治提供可靠依据。

It is necessary to study the distribution law of ＂three zones＂ of spontaneous combustion in goaf in order to prevent and control the spontaneous combustion of waste coal in goaf. Aiming at the distribution of spontaneous combustion ＂three zones＂ in fully mechanized caving face of Baozigou Coal Mine, this paper scientifically and rationally designs the monitoring scheme, studies the monitoring of oxygen concentration, temperature change and CO concentration change, and obtains the distribution law of ＂three zones＂ in 10101 working face according to the comparison between the monitoring results of oxygen concentration and temperature change. The reliable basis for spontaneous combustion control in goaf is provided.
