noise is produced when large machines are working in opencast mines, conveyor belts are running or trains are rolling. even the whirling up of dust is not always avoidable, especially in dry weather. with a package of technical and organisational measures, we therefore endeavour to avoid or minimise the nuisance to the neighbouring communities of the opencast mines.

Evaluation Of Belt Conveyor And Truck Haulage Systems In

Evaluation of belt conveyor and truck haulage systems in

in this paper, lca methods are used to evaluate the environmental impacts of belt conveyor and truck haulage systems in a hard rock open-pit gold mine. also, using global warming and acidification potential impacts, the paper tests the hypothesis that belt conveyor systems are more environmentally friendly than are truck haulage systems.
