WebTherefore the critical depth of burial, do, would be 6.2 ft which would be the distance from the free face to the center of the charge including the collar distance. Since the charge center is only 3.05 ft from the bottom end of the charge, a 3.05 ft collar would be used which includes the plug. WebScaled Depth of Burial (SDoB) is a calculation in blasting design that gives an indication of the amount of confinement of individual explosive… Liked by Siphosenkosi Nene You can always... jaz goodreau
