Demolition

from Wikipedia, the free encyclopedia

A blasting is the destruction of an object by explosives . It is used for military and civil purposes, such as the demolition of buildings , the extraction of mineral resources , the production of terrain depressions, tunnel construction , the connection of non-weldable metals with the help of blasting technology or the shaping of sheet metal by explosive cladding . Sometimes explosions are also carried out for criminal purposes, e.g. B. to steal money from machines. However, if the act only serves the purpose of destruction, it is usually not referred to as demolition, but rather as a bomb or explosive attack or the like.

execution

According to the law on explosives , explosions may only be carried out by trained specialist personnel, i.e. those authorized to blast . The training takes place at so-called demolition schools or in the military, disaster control ( THW ) and in mining in state-recognized courses. In Germany, the specialist knowledge is proven by a certificate of successful course participation. With this, the holder can receive a certificate of competence in accordance with § 20 or § 27 Explosives Act .

Other meanings

Technically, the word generally designates the separation of solid materials by introducing objects or substances with an expansive effect. So it is possible to blast stone apart by inserting watered wooden wedges , as wood expands with great force after watering. Inclusions of water that are frozen also break apart solid substances. In these cases there is no explosion , but breaks and parting lines occur.
