Sequential timing using the Maxclip 5 way clips.
4000ms Down-the-hole, 200ms surface delay.
Burden and Spacing of 500mm
No shockwave or air-blast
PPV of 1,88mm/s measured at 15m
fly rock less than 10m
muck pile on the face
fragmentation of 250-300mm.
Using Nxburst (Nonex) there is no back break or over break, leaving the hanging wall, foot wall and side walls competent (no fractures) for a safer mine.
Congratulations on great work!
