摘　　要：为了预防15108综采面自然发火，对采空区遗煤状况进行了分析，通过高抽巷喷撒MgCl2阻化处理采空区后部浮煤、内错尾巷和防灭火措施巷钻孔压注MEA泡沫控制14#和15#采空区浮煤。结果表明，在实施阻化防灭火综合措施后，采空区CO浓度有明显下降，未有自燃迹象，效果显著。Analysis of the status of the remained coal in gob area has been undertaken and the appropriate inhibitor has been selected for longwall face No. 15108 in order to protect the instantaneous combustion. The remained coal in gob area No. 14# and 15# was controlled by pressure injecting MEA foam from internally interlaced roadway and fire protection roadway while the remained coal in rear gob area was handled by spraying MgCl2 inhibitor in highly exhausted roadway. The result shows that the CO concentration is dramatically reduced and no instantaneous combustion has been observed any more after the comprehensive measures of fire protection by inhibiting are adopted.
