A High-Fidelity Modelling Method for Mine Haul Truck Dumping Process

Blog Article

Dumping is one of the main unit operations of mining.Notwithstanding a bar drain board long history of using large rear dump trucks in mining, little knowledge exists on the cascading behavior of the run-of-mine material during and after dumping.In order to better investigate this behavior, a method for generating high fidelity models (HFMs) of dump profiles was devised and investigated.This method involved using unmanned aerial vehicles with mounted cameras to generate photogrammetric models of dumps.

Twenty-eight dump profiles were created from twenty-three drone flights.Their characteristics were presented and summarized.Four types of dump profiles were observed to exist.Factors that influence the determination of these profiles include the location of the truck relative to the dump crest, the movement of the iphone 14 price chicago underlying dump material during the dumping process and the differences in the dump profile prior to dumping.

The HFMs created in this study could possibly be used for calibrating computer simulations of dumps to better match reality.
