zersprengen

Zersprengen is a German verb meaning to cause something to explode into fragments; to blast apart. It refers to the fragmentation of a solid object by a detonation or rapid release of energy. The term is used in mining, quarrying, construction, and demolition to describe controlled blasting designed to break rock or structures into smaller pieces for easier handling or removal. In practice, zersprengen involves placing explosive charges in drilled holes or within a structure, using delay detonators to control the sequence of detonations and the resulting fracture pattern. The design aims to maximize fragmentation while limiting flyrock, ground vibration, and dust, and it is governed by safety regulations and blasting standards.

The word derives from zer- indicating destruction and sprengen, to blast or rupture. In everyday language, zersprengen can also be used metaphorically to describe any process that causes something to break apart rapidly.

Common explosives include conventional high explosives, ammonium nitrate–based mixtures, and more specialized formulations. Modern practice emphasizes precise blast design, stope- or bench-by-bench sequencing in open-pit or underground operations, scaling of fragments, and environmental protection.

Risks include unintended rock movement, structural collapse, injuries, and environmental impacts. Training and licensing are typically required for personnel performing blasting work, and sites are subject to monitoring and permits.
