Experimental Study on Primal CO Desorption Effect Factors: External Causes

Carbon monoxide (CO) is a commonly used indicator gas to predict the risk of coal spontaneous combustion. However, the occurrence of primal CO in coal seam may result in error of prediction. Therefore, identifying the primal CO in coal seam is crucial to improve the accuracy of coal spontaneous comb...

description Carbon monoxide (CO) is a commonly used indicator gas to predict the risk of coal spontaneous combustion. However, the occurrence of primal CO in coal seam may result in error of prediction. Therefore, identifying the primal CO in coal seam is crucial to improve the accuracy of coal spontaneous combustion prediction. This paper conducts a laboratory experiment to research the regularities of primal CO desorption. Four analysis factors are introduced to represent the CO emission characteristics in different desorption stages. The result indicates that CO generated by different coal samples’ oxidation has big differences. Ambient temperature has little effect on CO initial emission concentration. CO concentration in the first one and first ten desorption hour increases regularly with the increase of crushing time, primal CO cannot be ignored especially in high temperature coal mines.
