Preface The idea of developing a haul road manual or collection of guidelines was initiated by the late Professor Muirhead at the University of Alberta in 1999. Support and financial contributions for this work were obtained from NSERC, SMART (Surface Mining Association for Research and Technology) ATCO Power, and Finning. Both Syncrude Canada Ltd. and Suncor Ltd. provided access to road ...

Abstract: Whilst considerable time and effort is expended on loader and truck haulage system selection and optimisation for an underground operation, comparatively less effort is applied when considering the design and maintenance management of the roadways on which the system is intended to operate. These roadways or declines should be considered an asset, and should, in conjunction with the ...

The overall approach to this project – 'Improving the resilience of surface mine haul roads', was to develop cost effective, 24/7 roading practice and engineering controls, including haul road material selection, design and construction practice, road maintenance management and circuit prioritisation for minimised rolling resistance (RR).

• The structural design provides haul road 'strength' to carry the imposed loads over the design life of the road without the need for excessive maintenance, caused by deformation of one or more layers in the road – most often soft, weak or wet in-situ materials below the road surface.

The haul road length varies widely from mine to mine. Temporary haul road lengths ranged from 0.5km to 10km whereas the length of permanent haul roads varied from 1.3km to 14km. Monenco (1989) reports a total of 50km in-pit and 180km of ex-pit roads for the 13 mines surveyed.
