摘　　要：采空区"三带"分布及变化规律的研究,是综放面自燃预测的基础.通过对常村矿2106综放面的综合观测,得到采空区气体、温度的分布及其在工作面推进过程中的动态变化.根据观测数据及所采煤层自燃的极限参数和工作面的开采条件等,确定了采空区"三带"的范围,并结合常村矿煤的自然发火期,确定了工作面不发生自燃的最小推进度,据此可以对综放面采空区自燃危险性进行预测.图4,表1,参10.Studying on regulation of 'three zones' distribution of mined-out area is the basis of predicting spontaneous combustion of coal.Through observation of workface 2106 in ChangCun coalmine,concentration of different gases and temperature of coal in different places in mined-out area are obtained.According to observation data,critic parameters of coal spontaneous combustion that can be obtained through experiment,and mining condition,etc.,'three zones' of spontaneous combustion is plot out. Connecting the range of 'three zones' with shortest duration of spontaneous combustion,smallest advancing velocity of the workface is determined.Danger of spontaneous combustion is determined through the above study eventually.4figs.,1tab.,10refs.
