Abstract

"The traditional approach to open pit mine planning has consisted of an iterative process of economic modeling, pit limit determination, pushback design and production scheduling. Even though truck haulage costs typically account for one-third to one-half of a mine’s total mining cost, the incorporation of optimal haulage planning into the mine planning process has largely been ignored due to the complication of calculating the haulage cost to transport a block of in situ material to its process destination. To aid the mine planning engineer, a suite of haulage planning tools was developed to facilitate solutions to haulage planning problems in the areas of economic modeling, haul road placement and fleet estimation by automating the process of generating haulage profiles and calculating cycle times.

The traditional mine planning process produces ultimate pit and pushback designs, surfaces representing mine topography over the life of the mine and stockpile phase designs. To automate the calculation of the haulage profile from a designed mine pushback across a mine topography to a stockpile, four haulage planning problems were solved: (1) the shortest representative haulage distance problem, (2) the shortest haul road location problem, (3) the haul road gate construction problem and (4) the cycle calculation problem. Solutions to these four problems enable the mine planning engineer to incorporate haulage optimization into existing, commercially available mine planning tools"-- Abstract, p. iii
