皇后煤业15105工作面采空区自燃三带划分技术研究

Research on Three Zones Division Technology of Spontaneous Combustion in Goaf of 15105 Working Face of Huanghou Coal Industry

煤矿开采过程中的煤层自燃是影响工作面安全开采的重要因素之一,即使在自燃倾向性很小的煤层,也会因为开采深度、开采方式、埋藏条件等因素,存在较大几率的煤层自燃危险。以盂县恒泰皇后煤业15105工作面为研究对象,进行采空区煤自燃三带现场观测,分析不同推进处遗煤自燃情况随时间、气体的变化规律,从而对煤自燃三带进行划分,确定出采空区遗煤自燃危险区域。

The spontaneous combustion of coal seams in the process of coal mining is one of the im⁃portant factors that affect the safe mining of working faces.Even in coal seams with a small tendency to spon⁃taneous combustion,there is a greater probability of spontaneous combustion risk due to factors such as mining depth,mining methods,and burial conditions.Taking the 15105 working face of Huanghou Coal In⁃dustry as the research object,conduct on-site observation of the"three zones"of coal spontaneous combus⁃tion in the goaf.Analyze the changing laws of spontaneous combustion at different degrees of advancement with time and gas,so as to divide the"three zones"of coal spontaneous combustion,and determine the risk area of spontaneous coal spontaneous combustion in the goaf.
