Explosive shock tube having lateral initiation properties

摘要

A modified explosive shock tube is provided which has a lateral energy output and hence may be used as a trunk line in a non-electric blasting network. The modified shock tube comprises a hollow, flexible plastic tube having a layer of energy-producing material on its inner surface and also having at intervals along its length, cuts or slits which penetrate the tube wall. The area of the slits has an overcovering of a waterproof material. When energized, the tube will burst at the area of the slits to release energy in a direction lateral to the tube axis.
