摘要：

The 400g and 600g class slurry explosives are inferior to conventional explosives in safety with the suspension method. On the angle shot mortar test of Eq. S-1 class, slurry explosives are also inferior. The ignitability of coal dust depends on the quantity of flash reducing agents or sodium nitrate. Methane ignitability changes with the ratio of water and salt, ammonium nitrate and water or ammonium nitrate and aluminum powder. Methane ignitability also changes with the increase or decrease of the density of slurry explosives.
