Control of Vibration and Blast Noise from Surface Coal Mining. Volume II.

摘要

A series of controlled experiments was conducted at four surface coal mines to study the effects of certain blast parameters upon the ground and air vibration. Preliminary scale-model blasts were conducted at a quarry to provide basic data. This report describes the experiments conducted at the mines and the variables evaluated are identified. The effects of the variables upon the peak amplitudes and frequency content of the seismic and air vibrations are included.
