LOW ENERGY FUSE

摘要

In a low energy fuse, the reactive composition on the inner wall of the tubing is substantially free of a metal fuel or quasi metal fuel and comprises a particulate secondary high explosive and a gas generating non-explosive particulate solid selected from barium peroxide, barium nitrate, potassium permanganate, potassium chloride or sodium azide. The gas generating solid renders the fuse safer for use in an inflammable or incendive atmosphere such as a coal mine.
