A short compilation of about 40 recent blasts in built up areas around houses, utilising millisecond delay “Nonel” detonators for superior vibration management.
Featured blasts are typically 20 – 50 holes covered with about 1 metre of soft fill and when fired the blast propagates sequentially through the connected holes, with an inter hole delay period of 25mS, this is evident by the way the blast ripples through the covered rock.
This video is dedicated to all those experts that keep telling me that "you just can’t blast anywhere near a built up area".
