Explosives load based on 1.0 g/cc. To achieve explosives load for other product densities, multiply load per foot by that product density. IMPERIAL Column Load Formula lbs / ft = 0.34 X De2 X d De = Diameter of Explosives in inches d = Density of Explosives in g/cc |
Example 0.84 g/cc in 5" hole Explosive Load = 8.51 X 0.84 = 7.15 lb/ft Explosives Column Diameter, inches | Explosives Load lb/foot | Explosives Column Diameter, inches | Explosives
