Transport of ore and overburden in open-pit mines is often performed with large haul trucks. Battery-electric operation trucks can significantly reduce the CO2 emissions fossil fuel dependence mining. This simulation study investigates feasibility economy operating battery-electrically, charging from an electric road system form overhead trolley lines. The used model verified against measuremen...

Suboptimal haul road management policies such as routine, periodic and urgent maintenance may result in unnecessary cost, both to roads and vehicles. A recent idea is to continually access haul road condition based on measured vehicle response. However the vehicle operating conditions, such as its instantaneous speed, may significantly influence its dynamic response resulting in possibly ambigu...

Previous measurements of whole-body vibration associated with earth-moving equipment at surface coal mines have highlighted the significance of the hazard. Considerable variability in measurement amplitudes, even within the same equipment type operated at the same site, has been noted. However, the measurements have previously been undertaken for relatively short durations. Fifty-nine measureme...

This paper describes a simple method for estimating haul road defect positions from alongside roads. It is a method that is cheap and easy to implement, needing only a minimal amount of field equipment and training. Observers are required to estimate the bearing and distance to a defect, and to record their location using a GPS receiver. All further processing is automated and can be done entir...

Drivers of mining trucks are exposed to whole-body vibrations (WBV) and shocks during the various working cycles. These exposures have an adversely influence on the health, c...

ABSTRACT Pope & Talbot Ltd., Arrow Lakes Timber Division, Nakusp, B.C. having no alternative options constructed a forest road with adverse haul grades up to 16%, to access a harvesting area. The company did not know the exact limitations of the adverse haul grade, but it did plan to use highway sized loads on this off-highway haul, thus sacrificing some productivity. When the road was complete...

The impact of fatigue is seen not only in its effect on job performance of haul truck operators but also on the health of the operator and the productivity at the mine site. Its impact can even extend outside of the mine site to the health and well-being of the surrounding community (Fourie et al., 2010). In this paper, a case study of a small surface mining organization is presented. The goal ...

This paper presents a haul truck alignment monitoring system that provides early warning signals to the operator when the truck is about to lose control. It is considered that a truck is in this condition when it crosses the centre of the road or veers to the side of the road at speed in an uncontrolled manner. The system provides different level of warnings to the driver and other haul trucks ...

LiDAR-derived digital elevation models can reveal road networks located beneath dense forest canopy. This study tests the accuracy of forest road characteristics mapped using LiDAR in the Santa Cruz Mountains, CA. The position, gradient, and total length of a forest haul road were accurately extracted using a 1 m DEM. In comparison to a field-surveyed centerline, the LiDAR-derived road exhibite...

Absfmcf-This paper describec the implementation of an autonomous navigation system onto a 30 tonne Load-Haul. Dump truck. The control architecture is based on a robust reactive wall-following behaviour. To make it purposeful we provide driving hints derived from an approximate nodal. map. For most of the time, the vehicle is driven with weak localization (odometry). This need only be improved a...
