Vibration and Explosion overpressure measurements and modelling
We have an impressive fleet of “Instantel minimate plus” vibration monitoring equipment with remote logging capability. When explosives are used to break rock in a mine, the blast produces both ground vibration and air overpressure (noise). In most cases the atmosphere selectively absorbs the higher frequencies from a blast, leaving relatively low energy (5 hertz) sound waves to effect structures.
