Normally, the diameter of a borehole is limited by the capabilities of the drill used to create it. As a rule, open-pit and coal strip mines using large drills will drill presplit holes that range from 9 to 12-¼ inches in diameter. Quarry and construction presplits are much smaller, generally ranging from 2 to 4 inches in diameter.
