..., these problems are fly rock, air blast, back break and ground vibration. Amongst all problems originated in blasting, because of stringent statutory regulations blasting induced ground vibration can lead into early mine closure. To measure ground vibration intensity in a blasting site, peak particle velocity...

... engineering in hazardous geo-environments Keywords: blasting, blast induced vibrations, vibration predictors, peak particle velocity 1 INTRODUCTION In sectors such as mining, quarrying, excavating tunnels and pipeline trenches, blasting is indispensible. Thus, these sec- tors are always prone to suffer from...

... A portable, stand-alone instrument especially designed for recording strong ground motion was used in this study to create a large database of peak particle velocities measured underground. A total number of 39 sites located in stopes mining Carbon Leader and Ventersdorp Contact Reefs were...

... ABSTRACT: Peak particle velocity of ground vibration has been globally accepted as a criterion of blast damage to surface structures, Investigations were carried out to study the effect of underground blasting on surface structures in the vicinity of six collieries under varying' geological...
