Abstract
The aim of this work is to fine out the explosion behaviors of ultra-fine coal dusts so that we can get insight into the explosion hazards of the ultra-fine coal dusts and improve safety in power plant and other industry that generate, process, use, or transport ultra-fine coal. All of the tests were conducted in a 5.125 litre explosion chamber in laboratory. The data recorded during each individual test include maximum explosion pressures, maximum rates of pressure rise, minimum explosion time. Based on the experimental data the significant influencing factors are discussed and some conclusions are drawn.
