Test method for the propensity of coal to spontaneous combustion

摘要：

The propensity of coal to spontaneous combustion demonstrates the inherent character of the oxidation capacity at normal temperature. Currently, based on simulating spontaneous combustion of coal using adiabatic oxidation and temperature-programmed experiment, many overseas countries test characteristic parameters of spontaneous combustion of coal, such as SHT, HR, R70, CPT, high-temperature activation energy, and so on. Oxygen adsorption method is used to test the absorbed oxygen at 30℃ in China. According to the deficiency of the present research using partial stage parameters to demonstrate the whole process, Oxidation Kinetics which reflects the entire dynamic process is put forward, through testing the concentration of oxygen in the outlet of sample vessel at 70℃ and CPT later. With results repeated well and simple manipulation, the method can reflect the self-heating character very well and thus has a vital significance for the prevention and control of the mine fire.
