Retard system solution on electric mining trucks
3rd IEEE International Symposium on Sensorless Control for Electrical Drives (SLED 2012), 2012Loss of dynamic brake is one of the important issues of AC electric mining trucks. The lack of dynamic brake reduces the safety and worries the truck driver. The driver may be forced to use the service brake, which increases the cost of repair and maintenance.

Mining truck scheduling with stochastic maintenance cost
Journal of Coal Science and Engineering (China), 2012Open pit mining operations utilize large scale and expensive equipment. For the mines implementing shovel and truck operation system, trucks constitute a large portion of these equipment and are used for hauling the mined materials. In order to have sustainable and viable operation, these equipment need to be utilized efficiently with minimum operating

Effects of mining truck traffic on cricket calling activity
The Journal of the Acoustical Society of America, 2019Anthropogenic noise is a global pollutant and several studies have identified its impact on wildlife. This research shows how the noise produced by mining affects crickets' acoustic communication. Two passive acoustic monitoring devices (SMII) were installed in a forest fragment located at 500 m from the Brucutu Mine in Brazil.

Vibration in operating heavy haul trucks in overburden mining
Applied Ergonomics, 2004The objective of this study was to determine if the vibration in sagittal (x), coronal (y) and vertical (z) axes of the seat pan of the heavy haul trucks used in overburden mining, and the vibration experienced by the drivers at the third lumbar and seventh cervical vertebral levels in operating these trucks exceeded the ISO standards, thereby posing ...
