praezisionssprengung with lock unerwuenschter side effect from detonations - erschuetterungen

摘要

A cushioned blasting system curtails or prevents seismic waves and damage caused by them to a certain region according to plan; it uses fibre fabrics or porous plastics as suppressors. These are applied to the explosives charge so that the section to be cushioned receives no detonation shock. In extreme cases, the stemming of a charge can be omitted so that the air acts as the stemming. This provides greater safety for the environment of blasting operations. There is no overbreaking in blasting of reinforced concrete or masonry structures. Up to 50% savings in cost have been recorded.
