This paper presents the preliminary results of a research work on procedures for the determination of optimal maintenace policies under imperfect repair assumption. The topic was motivated by a real data set on failures of off-road trucks used by a mining company. In particular, it is discussed the determination and practical implementation of an optimal preventive maintenance policy using the ...
Background: Exposure to vibration is one of the occupational agents that causes a variety of health effects. The aim of this study was to determine the association between exposure to human vibration and the physical performance of mining drivers. Methods: In the present study, 65 drivers working in one of the Iron Ore mines, were asked to complete the standard questionnaire for assessing th...
This paper discusses the design and deployment of low-cost Internet Things (IoT) in medium-scale open pit mines to optimise performance their mining small-scale trucks surface shovels. Low-cost IoT can be implemented operations automate collection process management information that is currently measured manually, replicating part results delivered by commercial Fleet Management Systems (FMSs) ...
Dump trucks are the main mean for hauling earth material within and outside of the construction and open-pit mining jobsites. The real-time monitoring of the material transportation trips is beneficial for proactive equipment management, volume estimation, and productivity measurement. The traditional manual observation is tedious, non-real-time, and expensive; therefore remote sensing technolo...
Transport of ore and overburden in open-pit mines is often performed with large haul trucks. Battery-electric operation trucks can significantly reduce the CO2 emissions fossil fuel dependence mining. This simulation study investigates feasibility economy operating battery-electrically, charging from an electric road system form overhead trolley lines. The used model verified against measuremen...
