The Technology of Forecasting and Predicting the Hidden Danger of Underground Coal Spontaneous Combustion
Coal has a large number of macromolecular compound as a combustible organic rock, when it happens oxidation reaction after contacting oxygen, not only the coals quality has changed but also it will present some chemical phenomena and external features. The hidden danger of coal spontaneous combustion is predicted by observing and analyzing those features, synthesizing its features and the differences at the different stage of development, so that it can provide reliable guidance to prevent underground spontaneous fire. The study of indicator gases to forecast and predict coal spontaneous combustion is more and more important to prevent the spontaneous combustion. For this reason, the paper, according to the indicator gases and critical value, systematically introduces the technology of predicting the hidden danger of underground coal spontaneous combustion such as detecting the carbon monoxide concentration, chromatographing the gas composition, detecting the coal temperature and infrared radiation detection analysis, which provides the guidance for the prediction of the coal spontaneous combustion.
coal spontaneous combustion indicator gases forecast and predict provide guidance
