A Field Study of Haul Truck Operations in Open Pit Mines

Abstract

This paper presents findings from a field study of the operation of haul trucks in two open pit gold mines. Qualitative results relevant to the haul truck operator’s work environment are presented, and the human factors challenges of the work are identified. Three specific issues that stood out from the study are discussed in detail. First, fatigue is identified as a major contributing factor to crashes and overall performance in open pit traffic, heightened by the specific work characteristics of a haul truck operator. Second, negative transfer is discussed as it interferes with the adaptation from one truck type to another: a consequence of inconsistent controls across different truck brands. Third, the under utilization of and the general posture of suspicion towards the dispatch system are reported, with a list of potential reasons related to automation characteristics.

Analysis of Factors, Which Influence the Cycle Time of Dumpers of Open Cast Coal Mines to Improve Production

“…Drivers used to meet other traffic at intersections and they are forced to stop the vehicle and there will be loss of time, consequently the cycle time of the dumpers is extended [10].…”

Automatic control of haul truck travel speed on open pits

“…BelAZ 75306 (www.belaz.minsk.by) Thus, the travel conditions represent a combination of the parameters and effects that influence the braking process, such as[5][6][7][8][9][10][11]:  Road conditions: longitudinal and transverse grade, road segment lengths and transition times, surface quality, visibility, etc. ;  Vehicle inclination: longitudinal-strike and transverse-dip;  Vehicle declination;  Regime of the vehicle movement: forward or reverse;  Centre-of-gravity: position, alterations in respect to time and travel distance;  Asymmetrical braking;  Dynamic and static loading;  Rimpull;  Rolling resistance;  Driver distraction and actions;…”
