摘　　要：针对戊9-10-16150复合煤层大采高综采工作面风量大、易自燃的特点,通过实测采空区内氧气含量和温度的分布规律,考察了工作面采空区立体"三带"的范围,并根据该工作面的特点制定了有针对性的防灭火措施,极大地缩小了采空区氧化带的范围,防止了采空区遗煤自燃。According to the characteristics of large air flow and easy self- ignition in compound seam at E9- 10- 16150 working face with large mining height,by measuring the distribution law of oxygen content and temperature in gob,the range of stereo ＂ three zones＂ in gob is analyzed,and measures for fire prevention and extinguishing are established according to characteristics of the workface,So the range of oxidation zone in gob is reduced greatly and spontaneous combustion of residual coal in goaf is prevented.
