How does an explosive work?
A general theory of explosives is that the detonation of the explosives charge causes a high-velocity shock wave and a tremendous release of gas. The shock wave cracks and crushes the rock near the explosives and creates thousands of cracks in the rock. These cracks are then filled with the expanding gases.
What is C4 made of?

What was the most powerful explosion in the world?
Tsar Bomba, (Russian: “King of Bombs”) , byname of RDS-220, also called Big Ivan, Soviet thermonuclear bomb that was detonated in a test over Novaya Zemlya island in the Arctic Ocean on October 30, 1961.

How many PSI can kill you?
Anywhere from 20 to 40 added pounds per square inch can be fatal, depending on the time it takes to wash over the body. At the high pressure shifts, the body just comes apart. There’s only so much trauma that flesh and bone can take.
What is the most explosive element?
The Chemical Most Chemists Won’t Touch Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state.
How are explosives used in the mining industry?
Explosives are used in underground mines and quarries to break coal and other rocks. An explosive is a solid or a liquid substance or mixture of substances which change themselves instantaneously into a large volume of gases at high temperature and pressure when a flame, heat or sudden shock (detonation) is applied to it.
Are there situations where a worker is responsible for explosives?
There are some situations where a worker is responsible for explosives. It can include things such as; ammunition, fireworks, detonators, etc. If this is the case extensive training is vital. There are about 65 pure chemicals that are considered explosive.
How are high explosives used in everyday life?
A high explosive explodes when a violent shock is applied to it with the help of a detonator; the process of oxidation does not proceed from particle to particle, but is instantaneous and the constituents react with high velocity. High explosives therefore produce a shattering effect.
Which is an example of an explosive substance?
Gunpowder is an explosive material made from a mixture of charcoal, sulfur and potassium nitrate. Classified as weak explosive (low explosive) gunpowder / black powder is often used in the manufacture of firecrackers or fireworks, or as an ingredient in firearms. That’s the list of explosive chemicals examples.
