Kuz-ram Model Excel Today

: A limestone quarry used baseline blast design: B=4m, S=5m, d=150mm, H=10m, q=0.55 kg/tonne, rock factor A=9. The primary crusher jammed frequently. Predicted P80 was 350 mm.

The is the most widely used empirical tool in the mining and explosives industries to predict rock fragmentation following a blast . Building this model in Excel allows blasting engineers to bridge the gap between theoretical blast design (burden, spacing, charge weight) and actual field results (oversize vs. fines).

Create a sieve size column (x) from, say, 1 mm to 1000 mm. : A limestone quarry used baseline blast design:

However, a common challenge arises:

I can share a basic .xlsx template I built — just ping me. Works great for capacity planning. 1 mm to 1000 mm. However
