摘要: 为了分析综放开采工作面自然发火规律,并对工作面自然发火危险性进行判定。选取滕东煤矿3下107综放工作面进行研究,首先以氧气浓度为主要指标,温度作为辅助指标,将107工作面进行自燃“三带”的划分,然后对3下107综放工作面进行沿空测温与取样观测,以此为依据建立自然发火危险性评价模型,并对该工作面进行自然发火危险性评判,研究表明:3下107工作面危险度为63.41%,该工作面属于极易自然发火工作面。Abstract: In order to analyze the laws of spontaneous combustion in the face of fully mechanized top-coal caving face, the danger of spontaneous combustion in the face is determined. This paper studies the 3 lower 107 fully mechanized coal caving face in Tengdong Coal Mine. Firstly, oxygen concentration is taken as the main index, and temperature is used as an auxiliary index to divide the 107 face into spontaneous combustion “three zones”, and then the temperature measurement and sampling observation along the goaf are carried out at the 3 lower 107 fully mechanized caving face to establish a spontaneous combustion risk assessment model based on this, and a spontaneous combustion risk assessment was carried out at the working face. The study showed that the hazard level at the 3 lower 107 working face was 63.41%. The working face belongs to the working face which is extremely easy to ignite naturally.
