Drill and Blast — A Necessary Evil Or? AusIMM

It is well documented that drill and blast outcomes affect the downstream mining processes of loading, hauling, crushing and grinding but it can also significantly impact on mine profitability via dilution, recovery percentage, lump generation (iron ore), fines generation (coal, iron ore), coal loss and final wall stability. Drill and blast must therefore be optimised...

H BLASTING IN SURFACE EXCAVATION

Blasthole diameter (D): Generally, the cost of drilling and blasting decreases as hole diameter increases. The relation between blasthole diameter and face height is approximately: D = 0.001 to 0.02 H Since iron ore is hard rock, and referring to Table 1 the rock factor A can be taken as 11. Assuming flyrock has to be controlled, Z=1.25.
