摘要
Abstract
Coal spontaneous combustion usually has a process from slow oxidation,accelerated oxidation,and then to severe oxidation.Therefore,in each stage,the methods of preventing and controlling fire are not the same.Therefore,in the predic-tion of coal spontaneous combustion,we can not copy the prediction indexes of other coal mines,nor can we only use CO as an index.Instead,we should select a comprehensive indicator gas index suitable for the prevention and control of coal spon-taneous combustion in combination with the actual situation,predicting the various stages of coal spontaneous combustion,so as to guide the formulation and implementation of coal spontaneous combustion prevention and control measures.On the ba-sis of using CO,we explore and find other olefins and alkane gases represented by C2 H4,C3 H6,etc.,and make a comprehen-sive prediction of the each stage and development trend of coal spontaneous combustion.关键词
