The use of ANFO originated in the 1950s. [3] It has found wide use in coal mining, quarrying, metal ore mining, and civil construction in applications where its low cost and ease of use may outweigh the benefits of other explosives, such as water resistance, oxygen balance, higher detonation velocity, or
Its other major use is as a component of explosive mixtures used in mining, quarrying, and civil construction. It is the major constituent of ANFO, a popular industrial explosive which accounts for 80% of explosives used in North America; similar formulations have been used in improvised explosive devices.
Extrudable explosives are an extremely viscous liquid, similar in properties to silicone based caulking materials used in construction. It is used in similar ways - stored in a container, then extruded out a nozzle into thin cracks, holes, or along surfaces. Some extrudable explosives can then be hardened using a heat curing process.

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 ...
