Dynamite is an absorbent material soaked in nitroglycerin.
Dynamite is one example of a chemical explosive. An explosive is anything that, once ignited, burns extremely rapidly and produces a large amount of hot gas in the process. The hot gas expands very rapidly and applies pressure.
Similarly, you may ask, how does a dynamite work?
Dynamite is formed into explosive sticks that feature a wick and a blasting cap. The wick is lit, which leads to a small explosion when it reaches the blasting cap. When the blasting cap explodes, the nitroglycerin then causes a much larger explosion.
Hereof, how is dynamite used in mining?
Dynamite. Dynamite is an explosive based on the explosive potential of nitroglycerin using diatomaceous earth as an adsorbent. The chief uses of dynamite used to be in construction, mining and demolition.
Chemical explosions may be distinguished from other exothermic reactions by the extreme rapidity of their reactions. In addition to the violent release of energy, chemical explosions must provide a means to transfer the energy into mechanical work. This is accomplished by expanding product gases from the reaction.
