Title: Study on Spontaneous Combustion Characteristics of Main Coal Seams in Xinjiang Shajihai Coal Mining Area
Abstract: In order to study the spontaneous combustion characteristics of the main coal seams in Xinjiang Shajihai Coal Mining Area,a programmed temperature-rise oxidation test device was used to study the critical temperature of spontaneous combustion of different coal samples and the variation law of the characteristic gas concentration of coal spontaneous combustion with temperature,and according to the test results,the oxygen-consumption rate and exothermic rate of coal samples at different oxidation stages were calculated.The study showed that the oxygen-consumption rate of the coal seams in Xinjiang Shajihai Coal Mining Area at different temperature-rise oxidation stages can be divided into two stages,the combustion-oxidation law of coal seams was determined,this thus provided the basis for judging the critical temperature of combustion-oxidation of coal seams.
