Abstract
In order to prevent coal mine fire caused by oxidation and heating in goaf of working face,taking the goaf of 10406 working face of Jin Bangde coal industry as an example,the spontaneous ignition law of coal seam is investigated.Based on the oxidation temperature experiment,the characteristic gas of coal seam spontaneous combustion prediction is determined,and the shortest spontaneous ignition period is calculated.The oxygen concentration in goaf is measured by the beam tube monitoring method,and the"three zones"range of spontaneous ignition in goaf is divided.Finally,according to the results of the division of"three zones"in the goaf,the limit advancing velocity of 10406 working face is calculated.It is found that the spontaneous combustion of coal in the goaf will not occur under normal working conditions.The study has important guiding significance for the prevention of mine fire in Jinbangde coal industry.关键词
