Estimating Raise Borer Productivity

A. New Raise Borer Cost Estimating Formula

Raise Borers, AC and DC

Price = aX^b, US Dollars

Where X is the cutter diameter in feet. Price includes basic machine; excludes crawler, starter pipe, cutter, pilot bit, and drive. Machines are sized by their rated cutter diameters. Cutters up to 40% larger than the rated size can be used on these machines depending on rock type.

AC Range in X, ft 4 to 15 a = 98631 b = 1.261

DC Range in X, ft 5 to 15 a = 186601 b = 0.9895

Cost based on M&S (Mine/Mill) Index of 1400

Based on:Mular, A. and Poulin, R.
