Abstract

A blasting cartridge comprises a closed tubular sheath, which contains a blasting explosive composition, wherein the wrapped material of the sheath has unsealed areas of overlap 13. When tamped in a borehole, the pressure on the cartridge causes it to deform to a shorter length and greater width so as to expand and fill the cross section or bore of the hole without exposing the composition. <IMAGE>
