Dynamite is a substance that can burn violently (i.e. explode) in a very short time. It is a substance that explodes by its own energy under the action of certain external energy. Generally, the chemical and physical properties of dynamite are stable, but no matter whether the environment is sealed or not, the amount of charge, or even under the condition of zero oxygen supply from the outside, dynamite will perform stable detonation work on the outside as long as there is strong energy (provided by primary explosive).

When dynamite explodes, it can release a large amount of heat energy and produce high-temperature and high-pressure gas, which can destroy, throw and compress the surrounding materials. Explosives have been more and more widely used in various departments of the national economy because of their advantages of low cost, saving manpower, accelerating engineering construction and working in special environment.
