Hi All MIP Families,
I have a couple of issues in achieving the crests of the walls with my current blasting operation. We do pre-split of 10m bench height at a range of 65-750 angle, 1.2m spacing, and medium to hard rock type. The explosive used is Riosplit WF 32*28 and 14 pieces are used in one hole tied to a 40g detonating-cord of 5m which acts as a stemming height to the surface. Initiated simultaneously connected with 6g on the surface.
I am looking for your professional advice in achieving my crest.
