Dynamite is considered a "high explosive", which means it detonates rather than deflagrates. The chief uses of dynamite used to be in construction, mining and demolition. However, newer explosives and techniques have replaced dynamite in many applications. Dynamite is still used, mainly as bottom charge or in underwater blasting.
Drilling and blasting is the controlled use of explosives and other methods, such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is often known as a rock cut.
The mining industry accounts for an estimated 90% of the more than 2.5 thousand tonnes (5.5 million pounds) of explosives used annually in the United States. [4] ANFO is also widely used in avalanche hazard mitigation .

World War I saw the adoption of TNT in artillery shells. World War II saw extensive use of new explosives (see: List of explosives used during World War II). In turn, these have largely been replaced by more powerful explosives such as C-4 and PETN. However, C-4 and PETN react with metal and catch fire easily, yet unlike TNT, C-4 and PETN are ...

Explosives have been used in surface mining and sub-surface mining to blast out rock and ore intended for processing. The most common explosive used in mining is ammonium nitrate. [47] Between 1870 and 1920, in Queensland Australia, an increase in mining accidents lead to more safety measures surrounding the use of explosives for mining. [48]
Detagel, which is very high in strength, is a specific example of a small diameter water gel explosive that is used for mining activities. [citation needed] Water gel explosives are frequently used as cartridge explosives because they are much easier to load into large casings. With water gel explosives, the slurry material can simply be poured ...
