The extractive industry is currently undergoing a transition toward operating models with reduced environmental impact and enhanced energy efficiency. This study aims to evaluate, through empirical data, the efficiency of an excavator equipped with a hybrid swing system compared to a conventional diesel-powered unit of the same class and performance level. The methodology involved a systematic monitoring period of 65 working days. To ensure a rigorous comparison, two crawler excavators in the 36-tonne class were d...

In terms of sustainability of mining, one of the decisive factors, in addition to economics, is safety. This mainly includes minimizing the effects of safety risk factors such as noise, vibration and technical seismicity, dustiness, the occurrence of harmful gases, etc. From this point of view, it is necessary to pay due attention to this area in research and try to maximize the protection of workers, but also the environment, from the effects of these risk factors resulting from the mining and subsequent mineral ...
