摘　　要：为了防治采空区煤炭自燃,采用热电偶测温和束管气体监测方法对五沟矿1021俯采工作面观测,得到采空区温度及氧浓度的变化情况。通过对温度和氧浓度实测结果的分析,并利用MIN-MAX方法优化,最终确定了采空区"三带"的范围。结合五沟矿煤的自然发火期,可以推算出工作面的临界推进速度,以此有效指导工作面的防灭火工作。In order to prevent against spontaneous combustion of coal in goaf, thermocoupte temperature measure ment system and bundle pipe gas monitoring system were applied to observe 1021 fully mechanized underhand min ing face of wugou coal mine, and the change conditions of temperature and oxygen concentration in goal were ob tained. Finally the range of ＂three zones＂ of goal was ascertained by analysis of the measured results of temperature and oxygen concentration and optimization of MINMAX method. In combination with the period of coal spontaneous combustion in Wugou coal mine, the critical speed of mining face could be calculated to efficiently guide fire pre vention work of mining face.
