Emulsion Explosives

Metric Loading Table

Explosives load based on 1.0 g/cc. To achieve explosives load for other product densities,

multiply load per metre by that product density.

Metric Column Load Formula

kg / m = (0.785 X De² X d) / 1000

Where: d = Density of Explosives in g/cc

De = Hole Diameter in mm

Example

0.84 g/cc in 127mm hole
Explosive Load: 12.66 X 0.84 = 10.63 kg/m
