The finer sizes have lower minimum explosible concentrations and higher explosion intensity. When particle sizes of coal dust are less than 75 μm,minimum explosible concentrations and explosion intensity approach a limiting value. In the concentration range measured ( less than 700 g/m3), maximum explosion pressures, maximum rates of pressure rise and explosion indices increase along with the increase of coal dust concentrations. Explosion intensity rapidly enhances along with ignition energy augmenting. Explosion reaction is weak while ignition energy is less than 1 kJ.
煤粉越细,其爆炸下限越低,爆炸烈度越大,但煤粉细到75 μm以下后,这种变化趋势趋缓;在所测浓度范围内(小于700 g/m3),最大爆压、最大压力上升速率和爆炸指数均随煤粉浓度增大而增大;爆炸烈度随点火能增大而迅速增强,点火能小于1 kJ时各煤样在不同浓度的爆炸都很微弱。
