Although much work has been done on design methods for pillars under various rock mass conditions, there seems to be a lack of consensus in terms of a uniform methodology that should be used throughout the mining industry. Moreover, there is no synergy between the coal, hard rock gold and platinum mines and the iron ore and manganese mines that use this method of mining. The purpose of this paper is to present the results of a preliminary analysis that is being carried out to try and find the 'Holy Grail' in the form of a generalised pillar design criterion or formula that is applicable to all mining environments and all modes of failure. Numerical modelling has been performed to ascertain the mechanism of failure in a range of cases and the effect that changes in pillar dimension may have had on pillar stability. At this time only square pillars have been considered.

The 68 km corridor is the first large greenfield freight rail infrastructure project to be carried out in South Africa since 1986, and will be operated by state-owned logistics provider Transnet Freight Rail (TFR). The project was designed by Transnet Capital Projects.
