“…A review by the National Institute for Occupational Safety and Health (NIOSH) reported a significant positive association between WBV exposure and LBP in 15 of 19 WBV studies reviewed by assigning its highest ranking descriptor of ‘strong evidence’ to the WBV-LBP relationship (NIOSH, 1997). A variety of field investigations have reported on WBV exposure for mining and quarry machinery (Smets et al, 2010; Mayton et al, 2008, 2009a; Eger et al, 2006; Kumar, 2004; Miller et al, 2000, 2004). Smets et al (2010) reported on a review of Canadian accident statistics for the Ontario Mining Industry, which showed that 16% of the traumatic injuries were associated with HT operation.…”

To further assess vibration exposure on haul trucks (HTs) and front-end wheel loaders (FELs), follow-up investigations were conducted at two US crushed stone operations. The purpose was to: 1) evaluate factors such as load/no-load conditions, speed, load capacity, vehicle age, and seat transmissibility relative to vibration exposure; 2) compare exposure levels with existing ISO/ANSI and EUGPG guidelines. Increasing HT speed increased recorded vibration at the chassis and seat as expected. Neither vehicle load nor vehicle speed increased transmissibility. Increasing HT size and age did show transmissibility decreasing. HT dominant-axis wRMS levels (most often the y-axis, lateral or side-to-side direction) were predominantly within the health guidance caution zone (HGCZ). However, several instances showed vibration dose value (VDV) above the exposure limit value (ELV) for the ISO/ANSI guidelines. VDV levels (all dominant x-axis or fore-aft) were within and above the HGCZ for the EUGPG and above the HGCZ for ISO/ANSI guidelines.

“…Of the remaining defects, most of these rarely triggered a response, except at higher (unladen) truck speeds owing to the low defect degree and extent scores. 15 Twenty three defects were situated close to more severe defects and no separate trigger could be discerned from these defects, since the truck was still in vibration owing to the effect of the associated defect. The repeatability of the vibration signatures was found to be associated with truck speed; at lower speeds less variation was evident.…”

The maintenance management of unpaved mine road networks varies widely, from small low tonnage operations where ad hoc techniques are applied, to extensive networks of roads subject to large numbers of high axle loadings, where haul road maintenance management systems (MMS) have been successfully implemented. However, for complex road networks where material is sourced and hauled from a large and highly variable number of loading points, the MMS becomes onerous. Since most large mines operate ultra heavy mine trucks with on board diagnostic data collation, relaying data within a broader asset management and centralised communication and GPS backbone, it was recognised that road condition could be monitored on a realtime basis and the data integrated within the centralised truck management system. This paper summarises the results of a number of field trials undertaken to prove the concept of realtime road maintenance management, using truck derived multisensor data capture. The paper concludes that truck on board multisensor data integration with the existing mine communication and asset management systems can provide the basis for a realtime mine road MMS, with resultant improvement in service and reduction in total road user costs.

Workers who operate mine haul trucks are exposed to whole-body vibration (WBV) on a routine basis. Researchers from the National Institute for Occupational Safety and Health (NIOSH) Pittsburgh Mining Research Division (PMRD) investigated WBV and hand-arm vibration (HAV) exposures for mine/quarry haul truck drivers in relation to the haul truck activities of dumping, loading, and traveling with and without a load. The findings show that WBV measures in weighted root-mean-square accelerations (aw) and vibration dose value (VDV), when compared to the ISO/ANSI and European Directive 2002/44/EC standards, were mostly below the Exposure Action Value (EAV) identified by the health guidance caution zone (HGCZ). Nevertheless, instances were recorded where the Exposure Limit Value (ELV) was exceeded by more than 500 to 600 percent for VDVx and awx, respectively. Researchers determined that these excessive levels occurred during the traveling empty activity, when the haul truck descended down grade into the pit loading area, sliding at times, on a wet and slippery road surface caused by rain and overwatering. WBV levels (not normalized to an 8-h shift) for the four haul truck activities showed mean awz levels for five of the seven drivers exceeding the ISO/ANSI EAV by 9–53 percent for the traveling empty activity. Mean awx and awz levels were generally higher for traveling empty and traveling loaded and lower for loading/dumping activities. HAV for measures taken on the steering wheel and shifter were all below the HGCZ which indicates that HAV is not an issue for these drivers/operators when handling steering and shifting control devices.
