A study of the effects of the maintenance system at an open cast iron ore mine

A research report submitted to the Faculty of Engineering and the Built Environment,
University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for
the degree of Master of Science in Engineering
Johannesburg 2017 / The study assesses the drilling, loading and trucking stages of the mining cycle of an
iron ore mine situated in the Northern Cape province of South Africa for the period of
1 January to 30 June 2011. The purpose of this study is to investigate the effect of
increasing reliability and maintainability of mining equipment in an effort to increase
throughput of iron ore. The data processing indicated that both availability and
utilisation are contributing to the sub-optimal performance of the mine. Data
regarding reliability (MTBF), maintainability (MTTR), planned and unplanned
maintenance was analysed, and this provided input for the simulation model. The
intention of the simulation model is to simulate scenarios of proposed improvement
in MTBF and MTTR through increasing planned maintenance activities. A simulation
model provides insight regarding where to invest in interventions. It is determined
that the drilling equipment is the problem area. / MT2018
