Non-Incendive Rock-Breaking Explosive Charge

Details

• Personal Author:
  Mainiero, Richard J.
• Description:
  Non-incendive explosive charge for use in flammable atmospheres includes a layer of damp salt as quenching material surrounding a charge enclosed in an inner housing. An outer housing is strong and pliable, being formed of reinforced rubbery material, to resist rough handling yet to be sufficiently pliable to conform to irregular boulder surfaces. The outer housing is pancake-shaped to provide increased contact area and stability. The relatively flat shape further permits insertion of the charge in crevices between boulders.
