摘要
通过对淮南某矿121101工作面采空区的观测,得到了采空区各种气体的分布情况与采空区气体成分及其体积分数随工作面推进所发生的动态变化情况,以氧气浓度法及以观测的CO体积分数变化作参考,并利用MIN-MAX优化理论划分出采空区"三带"的范围,结合121101工作面实际情况和确定的"三带"范围,相应地提出了三相泡沫防灭火措施,可以有效地防止遗煤自燃。
Through the observation of No.121101 face in a certain coal mine, the gas distribution CO volume fraction, then the ＂three zones＂ is divided with MIN-MAX theory, the measures of fire prevention and control with three-phase-foam are proposed according to the ＂three zones＂ and the actual situation of No.121101 face,it can prevent the spontaneous combustion of residual coal effectively.
