Determination of minimum ignition temperature of coal dust of Co Kenh mine 2, Kim Boi mineral joint stock company

Abstract

Coal dust fires and explosions are extremely serious problems and always pose a risk in underground coal mines. Determining the basic parameters of coal dust combustion and explosion properties allows us to assess the risks during production and select necessary measures to prevent this hazard. One of the parameters directly related to the risk of coal dust fires and explosions is the lowest ignition temperature of coal dust. Based on the experimental results with coal dust samples taken at seam 2 of Co Kenh mine of Kim Boi Mineral Joint Stock Company, the author has determined the lowest ignition temperature of coal dust of seam 2.
