Seismo-Acoustic Method of Investigating the Effect of Shotfiring on the Roof of Underground Workings
In recent years, various mining problems have been studied to an increasing extent using the seismoacoustic method. In this method, we record and study the natural audio-frequency vibrations arising during fracturing of rocks under the action of rock pressure , and also the elastic vibrations excited in the rocks by external sources such as explosions .
