Rock Falls

Effective support for tabular stopes Continuation Project 2
The single largest cause of injuries and fatalities suffered by the workforce in South African gold and platinum mines is rockburst and rockfall hazards. The majority of these rock-related fatalities (± 56 per cent) occur in the
Effective support for tabular stopes Continuation Project
This project aims to develop an effective face support system to minimise rockfalls in rockfall-prone mines.  The primary output of this phase1 of the project was to develop and surface test a technology demonstrator roof support unit
Effective support for tabular stopes
This project follows on from project GAP 813, Effective Roof Support for Tabular Stopes and GAP 708, The Design and Development of an Effective Support System for Tabular Stopes in Gold and Platinum Mines.  The primary output of this
Development of an effective pinch bar
A significant proportion of rockfall accidents occur during re-entry into a workplace, when the initial inspection and making safe procedures are carried out to stabilise the rock before work in the area begins.  The reason is that
Development of a smart rockbolt
Development of a method to estimate coal pillar loading
The primary goal of this project was to determine the accuracy and validity of the Tributary Area Theory (TAT) and to provide better estimates of pillar load using numerical modelling and other tools. Literature review highlighted
Development of a method to determine in-situ principal stresses
Developing industry guidelines for the design of pillars in coal mines
This was a unique SIMRAC project in the sense that it did not address an expressed technical need explicitly. Rather, it afforded the opportunity for scientific discussion and exchange of ideas that could result in the identification of
