The most appropriate design parameters were determined as 15 m hole length, 102 mm hole diameter, 3–3.25 m burden, 3.5–3.75 m distance between holes and 3–3.5 m stemming length. The acceptable cost interval for similar rock units was proposed by deriving the graph of the relationship between blasthole diameter and total unit cost.
