Driving an unloaded bucket resulted in significantly higher levels of vibration exposure than with a loaded bucket.
Although it is not possible to conclude that high levels of WBV exposure were the only cause of the reported neck and back discomfort, vibration levels experienced by the underground mining load-haul-dump ( LHD) operators indicated health risks were likely to develop, with a higher probability of injury to the back. Analysis of all operators’ injury profiles and their vibration profiles will be important in future studies in order to determine whether these variables are related. The mining industry will need to consider a number of different intervention strategies to have an impact on injury...
Le niveau vibratoire et sonore des équipements miniers n'est pas considéré lorsque vient le temps de choisir le matériel
Dans cette étude, plusieurs recommandations visant à réduire l’exposition des travailleurs miniers au bruit et aux vibrations sont formulées. Un total de 28 équipements miniers répartis dans 8 mines souterraines québécoises a été évalué. Pour les vibrations globales du corps, les équipements à risque élevé (pour une exposition quotidienne de 8 heures) sont les rétrocaveuses (sur rails et sur roues), l’opération d’une foreuse à béquille sur...
Noise Control in Underground Metal Mining
This document is for operators, safety personnel, and mechanics in the mining industry who are not specialists in noise control engineering or acoustics. Evaluations of successful and unsuccessful attempts at controlling noise on several large, underground metal mining machines are detailed to illustrate the basic principles of noise control. Once personnel understand the guidelines and principles of noise control, they will be able to evaluate the extent of a noise problem; determine the best approach to the problem; and apply the most appropriate solution.
