Blasting mats are used when explosives are detonated in places such as quarries or construction sites. The mats are placed over the blasting area to contain the blast, suppress noise [1] and dust as well as prevent high velocity rock fragments called fly rock (or flyrock) from damaging structures, [2] people or the environment in proximity to the blast site.

Rock blasting in Finland. 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.
Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay), and stabilizers. [1] It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht, Northern Germany, and was patented in 1867.
Access mats may also be used in other, non-traditional settings, such as providing access for cattle to water troughs where muddy conditions may prove detrimental to the livestock; [4] for home owners who need access to buildings under construction before driveways are poured; to create temporary parking; [24] or to provide nature enthusiasts ...

A blast pen was a specially constructed E-shaped double bay at British Royal Air Force (RAF) Second World War fighter stations, being either 150 ft (46 m) or 190 ft (58 m) wide and 80 ft (24 m) front-to-back, accommodating aircraft for safe-keeping against bomb blasts and shrapnel ...
Dry-ice blasting used to clean a rubber mold. Dry-ice blasting is a form of carbon dioxide cleaning, where dry ice, the solid form of carbon dioxide, is accelerated in a pressurized air stream and directed at a surface in order to clean it.
In paint-stripping, ice blasting is used to overcome the cohesive bond of the coating. Depending on the paint or makeup of the bond, some coatings cannot be cleaned. Ice blasting is useful in removing lead paint, as it poses the least danger. Ice blasting has the lowest level of airborne contaminants for blasting technology in removing lead paint.
