Abstract: A stable extrudable non-azide crash bag propellant composition for generating high quality nitrogen gas and a low temperature process for producing the same from an extrudable mass containing an effective amount of a cellulose-based binder.

Abstract: 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.

Abstract: Thermostability, age stability, and ignition property at low temperatures of a W/O type emulsion explosive are remarkably improved by incorporating a chelating agent in the W/O type emulsion explosive.

Abstract: A gas-retaining agent having a particle size of 177-3,000 .mu.m is effective for improving the safety of water-in-oil emulsion explosive compositions against methane and coal dust and for improving the sympathetic detonability of the explosive compositions without deteriorating their strength.

Abstract: A gas-retaining agent consisting of bubble assemblies, each bubble assembly being one particle consisting of a large number of bubbles agglomerated into the particle, is effective for improving the safety of water-in-oil emulsion explosive compositions against methane and coal dust, for improving the sympathetic detonability of the explosive compositions and for lowering their detonation velocity without deteriorating their strength.

Abstract: Water-in-oil explosive compositions containing perchlorates and occluded air are provided which are detonable by a standard No. 8 blasting cap and which contain from about 14 to about 20 weight percent water, from about 3 to about 7 weight percent fuel, from about 56 to about 63 weight percent ammonium nitrate, from about 2 to about 12 weight percent of another inorganic nitrate, and from about 3 to about 12 weight percent of an inorganic perchlorate. The fuel material further comprises from about 0.5 to about 1.5% of a water-in-oil emulsifier, from 0 to about 1% oil, and at least 2% wax, based upon the weight of the emulsion.
