摘要
通过对耿村煤矿开采的二3煤层综放工作面采空区容易自然发火的原因分析,得出了综放工作面CO涌出规律,构建了防灭火技术体系,确定了综放工作面采空区自然发火的标志性气体CO浓度临界值为100×10-6,保证了工作面的安全推进,对类似矿井具有借鉴作用。
Through the analysis of easily spontaneous combustion reasons at gob of the fully mechanized caving face in Gengcun mine No.鈪? seam.The paper gets the CO emission laws of fully mechanized caving face,constructs the fire extinguishing and prevention technology system,and determines that the critical value of index gas CO concentration is 100 ppm in gob of the fully mechanized caving face,which ensures safety advance of working face and provides reference to the similar mine.
