Ground and Air Vibrations from Blasting.
Subsection 11 8 in SME Mining Eingineering Handbook 1:11-99to11-112
This review describes the problems of ground vibrations and noise produced by surface and underground blasting. Emphasis is placed on seismic and airblast damage to structures, and the generation andpropagation of seismic energy produced by mining, quarry, and excavation blasting. Ground motion and airblast damage criteria from Bureau of Mines bulletin 656 are discussed in addition to instrumentation and methods for minimizing airblast annoyance complaints. Recommended is a maximum safe ground vibration level of 2 in/sec for residential structures of normal seismic damage risk, and an airblast caution threshold of 0.5 Psi overpressure for properly mounted, strainless glass panels.
