MOTHEMELA, P.R.  e  CHABEDI, K.. Campaign mining set-up for waste stripping at New Vaal Colliery. J. S. Afr. Inst. Min. Metall. [online]. 2013, vol.113, n.4, pp.311-312. ISSN 2411-9717.

The objective of the investigation is to optimize the truck and shovel operations for pre-stripping at New Vaal Colliery by introducing campaign mining. The aim of campaign mining is to improve the efficiency of the loading, hauling, dumping, and maintenance operations which are critical to the success of truck and shovel operations. The current loading (single-sided loading method), hauling, and dumping operations at New Vaal Colliery were found to be inefficient. Time studies were used as a major indicator to highlight the inefficiency of the truck and shovel operations, and it is recommended that an improved loading configuration, hauling, and dumping operations be implemented by using campaign mining. It is also recommended that a service truck be used to maintain the pre-stripping fleet in order to reduce travelling times to the main workshop. As expected, the improved operating conditions will lead to an increase in pre-stripping production.

Palavras-chave : campaign mining; efficiency; bank cubic metres (BCMs); truck and shovel.
