Alan Rubens Sa Filho
This work applies quantitative reliability methodologies (LDA and RAM Analysis) to evaluate maintenance scenarios for wagon tipplers, analyzing failure behavior and item criticality in the rotation and wagon-positioning systems.
Anderson da Silva Garcia
This work consists of applying Reliability Engineering tools such as RCM, RAM Analysis and FMEA/FMECA to model and identify bottlenecks originating in maintenance-engineering processes, planning/control and activity…
Carlos Dalmiro
This study investigates the application of reliability simulation to forecast operational production in mining, focusing on how variability in asset performance — excavators and loaders — affects actual output. By…
Cássio Maciel Lemos
This work addresses the application of Reliability-Centered Maintenance (RCM) to the FMC Type 1 Master Control Station (MCS) control system used in the Búzios field. The MCS is a critical component for controlling…
Fábio Augusto Brito dos Santos Sousa
A methodical evaluation of hydraulic-cylinder performance for a surface-miner fleet using contour plots. The performance of new and refurbished hydraulic cylinders was analyzed using Life Data Analysis (LDA) and…
Ítalo Clemente Rodrigues
The objective of this work is to analyze the evolution of reliability for a long-distance conveyor belonging to the main asset of Vale’s S11D plant after implementation of improvements identified from the loss…
Karla Monique Cruz Bernardino
Auxiliary mining-support equipment plays a crucial role in operational efficiency and safety. The fleet includes several types of road-going equipment such as dump trucks, diesel service trucks, lubrication service…
Leandro Rocha Lopes
The railway-of-the-future vision calls for increasingly intensive use of onboard or wayside sensors for asset monitoring. In line with this approach, the Estrada de Ferro Carajás (EFC) uses wayside equipment to…
Luiz Claudio Henriques da Silva
This work aims to introduce Reliability Engineering into a condition-based maintenance scenario that has been questioned by subject-matter specialists because of its inefficiency. Reliability Engineering is expected…
Ney Miller Monteiro Neves
This work is a case study of reliability modeling using Life Data Analysis (LDA) applied to a set of items in the motorized wheel of an off-highway truck model used in a copper-mining operation in Pará, with…
Roberio Fonseca Padilha Júnior
This study investigates the influence of motivation on the quality of maintenance records, with a focus on the reliability of information documented in work orders. Based on Expectancy-Value Motivation Theory, the…
Thiago Mota Morais
The mining sector faces constant challenges related to operational efficiency and equipment reliability. Machine availability and reliability are critical factors for ensuring continuity and productivity in mining…
Vilderson Dias
An integrated strategy that combines methodologies such as FMEA, RCM, LDA and RCA with data analysis to ensure asset availability. By aligning reliability engineering and maintenance, the proposal promotes a systemic…
Vinicius Santa Clara Ucelli
Belt conveyors represent Samarco’s largest asset population and account for the highest mechanical-maintenance costs. This study addresses excessive wear as the primary failure mode, requiring a structured mitigation…
Wanderson Cipriano de Alcantara
The CBMM HP Oxide plant faced the challenge of increasing production from 6,300 tons in 2023 to 8,000 tons in 2024. To overcome unplanned shutdowns, Maintenance Engineering implemented reliability concepts and…
