Melesse Eshetu Moges Daniel Todt Arve Heistad Treatment of Source-Separated Blackwater: A Decentralized Strategy for Nutrient Recovery towards a Circular Economy The paper is an edited version of that presented at the `Maintenance in mining conference` 16-19 March 1998, held in Bali, Indonesia. Major results included: improved availability (and reliability) of all opencast fleets, improvements in rear dump availability reduced maintenance man-hours for opencast fleets and increased availability of the coal handling and preparation plant. Some improvements became almost immediately apparent, others were quite gradual.
The programme involved implementation systems of key performance indicators (KPIs), benchmaking, condition monitoring, work planning and control, failure analysis and maintenance audit. recently developed a maintenance improvement programme, described in this article. The South Blackwater operation consists of two opencut mining areas and two underground mines (Laleham and Kenmure) near Blackwater in central Queensland, all of which supply coal to a central coal preparation plant.
