Controlled blasting is the carefully designed and successive placement of explosives with timed sequences of detonations to safely excavate low-tensile strength materials to a defined surface. It may be utilized to conduct rapid removals of materials, while minimizing the risk of varied adverse impacts.

Blasting is an effective procedure, because chemical energy of the explosives is rapidly used to perform work. Two techniques utilize this rapid energy release: controlled blasting of low-tensile strength materials (rock and concrete) to be fractured and displaced to more easily processed sizes; and severance of metal frameworks, which deploys linear shaped charges detonated at discrete locations allowing the framework to be dismantled and displaced.

The performance of blasting and the potential risk of adverse impacts for both of these techniques are determined by several parameters, and confinement of the explosive charges is a major factor. Controlled blasting confines the...
