摘　　要：为了预防采空区自然发火的发生,以煤峪口矿C3-5^(#)煤8101工作面采空区为研究对象,按照O_(2)浓度划分指标,通过现场实测和数值模拟两种方法,对采空区自燃“三带”分布规律进行研究。确定了采空区自燃“三带”范围,并计算了工作面安全推进最小速度为0.86 m/d。工作面实际推进速度略大于最小推进速度,需对采空区氧化带进行惰化处理,以确保工作面的安全开采。In order to prevent the occurrence of spontaneous combustion in the goaf,taking the goaf of the C3-5~# coal 8101 working face in Meiyukou Mine as the research object.According to the O_(2) concentration division index,the distribution law of the "three zones" of spontaneous combustion in the goaf is studied through on-site measurement and numerical simulation methods.The range of spontaneous combustion "three zones" in the goaf is determined,and the minimum safe advancing speed of the working face is calculated to be 0.86 m/d.The actual advancing speed of the working face is slightly higher than the minimum advancing speed,and it is necessary to inert the oxidation zone in the goaf to ensure safe mining of the working face.
