Truck-Shovel fleet, as the most common transportation system in open-pit mines, has a significant part of mining costs, for which optimal management can lead to substantial cost reductions. Among the available dispatch mathematical models, the multi-stage approach is well suited for allocating trucks to respected shovels in a dynamic dispatching program. However, with this kind of modeling sequ...

Haul trucks have the potential to generate large amounts of respirable dust. This respirable dust has been shown to be a health hazard to personnel, especially if it has a high silica content. Lack of dust sampling data from haul trucks prompted the completion of a study to quantify respirable dust concentrations. These field studies were conducted measuring instantaneous respirable dust at sta...

During the last decade, mining companies and mobile equipment manufacturers have pursued improved efficiency, productivity, and safety in underground mining operations by automating some of the functions of underground vehicles. This paper describes the implementation and successful field testing of a new infrastructureless guidance system for autonomous tramming of centre-articulated undergrou...

This paper examines various control locations in heavy mining vehicles. Three trucks have been tested on a skid pad in both clockwise and anticlockwise directions. The skid lengths were measured after each trial. The primary focus of the study was the positioning of various controls and their relevance to various skid lengths. Some additional measures such as NASA-TLX scales were also used to m...

The commercial industries of agriculture, mining, construction, and material handling employ a wide variety of mobile machines, including tractors, combines, Load-Haul-Dump vehicles, trucks, paving machines, fork trucks, and many more. Automation of these vehicles promises to improve productivity, reduce operational costs, and increase safety. Since the vehicles typically operate in difficult e...

That is the daily challenge for the operators of the giant dump trucks used in surface mines. As a result, each year, an average of 20 accidents and three fatalities occur involving collisions between a piece of surface mining haulage equipment and either a smaller vehicle, a worker, or some other object. Another 21 accidents occur and three mining equipment operators are killed each year when ...

Mining haul trucks comprise the majority of the equip­ ment used in underground limestone mining operations and are known to emit high levels of noise. A previous study conducted by the National Institute for Occupational Safety and Health (NIOSH) indicates that 70-90 % of all miners have a noise-induced hearing loss (NIHL) great enough to be classified as a hearing disability b y retirement ag...
