Abstract
The invention indicates improvements in respect of blasting charges with directed blasting action for linear cutting or demolition purposes, wherein a rod 1 formed by a composite of explosive material and a first flexible material has a V-shaped groove 2 with a lining 5 made from a composite of particulate metal and a second flexible material. The metal can be constituted by copper and the first and second flexible materials preferably comprise the same components. The blasting charge can comprise a casing 6 having a distancing section 7,8, which has a contact surface 12 for bearing contact against a work surface 10, which contact surface lies parallel with the outer edges 9 of the lining 5 and is situated at a distance from these to maintain an optimal standard spacing. The casing can further comprise a groove-filling section 17, made from low density material, which can be constructed from a flexible material, such as expanded polyethylene, in one piece with the casing. <IMAGE>
