Therefore the difference in gravitational weight between military and improvised explosive devices can result in up to 45% reduction in explosive weight. 2. Velocity of detonation. Detonation velocity is one of the most important factors in assessing the peak blast pressure and impulses.
They are normally employed in mining, demolition, and military applications. They can be divided into two explosives classes differentiated by sensitivity: primary explosive and secondary explosive. The term high explosive is in contrast with the term low explosive, which explodes (deflagrates) at a .

May 08, 2017· Explosives have been used for blasting purposes in civil engineering, military, and mining applications dating back to the ninth century. Previously, black powder was the only explosive available, we''ve progressed a lot and discovered many alternatives during the Industrial Revolution.
Explosive materials are produced in numerous physical forms for their use in mining, engineering, or military applications. The different physical forms and fabrication methods are grouped together in several use forms of explosives.. Explosives are sometimes used in their pure forms, but most common applications transform or modify them.

Combustion (burning) is a process by which energy is released. Deflagration and detonation are two ways energy may be released. If the combustion process propagates outward at subsonic speeds (slower than the speed of sound), it''s a deflagration. If the explosion moves outward at supersonic speeds (faster than the speed of sound), it''s a detonation.
Water gels and slurries may be either explosives or blasting agents. The many industrial and military uses for explosives and blasting agents—ranging from earth moving to seismic wave generation to materials modification to munitions to propulsion—have generated a host of sophisticated and specialized explosives products and delivery packages.
