摘要
在自燃发火期较短的煤层中布置的综放工作面,开采期间受地质条件限制推进速度慢,容易造成采空区自燃发火。针对兖矿集团济宁三号井煤矿53下06综放工作面采空区自燃隐患的分析,提出了治理方案,并在短期内治理了采空区内的自燃隐患。
In top coal caving longwall faces arranged in coal seams with prompt risk of spontaneous combustion, face advancing rate is always slowed down by geological conditions during mining. This may result in spontaneous combustion in the goal. On the basis of the analysis of the risk of spontaneous combustion in active goal in 53lower 06 top coal caving longwall face in Jininng No. 3 Coal Mine, Yankuang Group, a control scheme is proposed in this paper. According to this paper, the hidden risk of spontaneous combustion in the goal area is brought under control in a short time.
