Abstract: This study was conducted to determine the effect of charge shape (cylinders with different aspect ratios) on the geometry of explosion-produced craters. For charges having a constant scaled depth of burial (in this case approximately 0.5 m/kgl/3.4) and an overall length less than 0.4 m/kgl/3.4, the apparent crater volume and the overall shape of the apparent crater remained essentially unchanged for aspect ratios that ranged from 1 to 8. Since charges can be configured with aspect ratios up to 8 without significantly affecting crater shape or volume, it is possible to reduce drilling costs associated with charge emplacement in that drilling costs depend on penetration rate and penetration rates increase as hole diameters decrease. In an excavation program in which many holes are required, cost reductions could be substantial.
