NELWAMONDO, P.  and  PRETORIUS, J.H.C.. Application of the event chain project management methodology to a mining stope. J. S. Afr. Inst. Min. Metall. [online]. 2018, vol.118, n.12, pp.1233-1242. ISSN 2411-9717.  http://dx.doi.org/10.17159/2411-9717/2018/v118n12a1.

Although South Africa possesses more than 80% of the world's platinum reserves, its reputation for reliability in supplying platinum to global markets is under threat. This is due to the 49% decrease in output per worker (1999-2014), while the domestic costs have risen by more than 10% annually for the past 5 years. In addition, the continued decline in the commodity price by 38.3% (2012-2016) has resulted in a significant portion of the sector producing at a loss in 2015. The Chamber of Mines (now the Minerals Council of South Africa) has suggested that solutions to improve productivity and reduce cost pressures are required. This research aims to provide operational excellence through the application of event chain project management (ECPM) to improve productivity and reduce operational costs. A case study was used to carry out research in platinum mines, with data collected using a motion-time study to measure the current efficiency of operations in each mining stope through actual activity durations. The results indicate that through the application of the event chain project management methodology, risks affecting the mining stope schedule can be managed, the efficiency of operations was improved by reducing the time spent on each activity, productivity was increased by shortening the project duration, and operational costs were reduced in the process.

Keywords : event chain project management methodology; productivity; mining stope; risks; uncertainty.
