Abstract
One of the main problems of effective use of water-containing explosives (WCE) in various mining and geological conditions and especially when blasting waterlogged massifs is the stability of aquatrinitrotoluene charges. When mixing a hot oxidizer solution (HOS) in mixing and charging machines with granulated or flaked TNT, the latter, having the density of granules p = 1,48+1,5 g/cm3, cannot be kept suspended in the explosive mixture, since the density of HOS does not exceed 1,4 g/cm3. As a consequence, there is a stratification of water-filled explosives, which leads to a change in the energy and detonation characteristics of explosives, to a deterioration of bottom penetration, to an increase in the yield of oversized material.
