Measurement of Airblast Produced by Surface Mining.
Proc 51st Ann Meeting AIME University of Minnesota, Duluth, Minnesota, 1978 :26-1 to 26-12
The surface mining industry is experiencing increasing problems in the form of complaints about vibrations from blasting. In many cases complaints are made at great distances from the blast, where ground vibration levels are low. Problems with confinement and adverse weather conditions can cause airblast to propagate large distances, creating a blast effect that is difficult to control. The objective of current airblast research is to determine the most appropriate measurement methodology for blast-produced noise based on structure response and human annoyance.
