Develop guidelines for the design of pillar systems for shallow and intermediate depth, tabular, hard rock mines and provide methodology for assessing hangingwall stability and support requirements for the panels between pillars

Author: Haile, AT ; Jager, AJ Date: Dec 1995 The overall view of the research being conducted at Impala platinum was to improve pillar design techniques through a rock testing programme, underground instrumentation and back analysis. The laboratory rock testing programme has provided a ... Read more
Rock mass condition, behaviour and seismicity in mines of the Bushveld igneous complex.

Author: Haile, AT ; Jager, AJ Date: Dec 1995 This project report gives an overall view of the rock mass environment of the Bushveld complex and influence on the mine design practices. The main focus of the project was to survey the currently available data and conduct further analysis ... Read more

Author: Haile, AT ; Jager, AJ ; Wojno, L Date: Dec 1995 This project report addresses the issue of strata control in tunnel excavations with the aim of improving the stability of the excavation through improved design methodologies and support systems. Read more
Strata control in tunnels and an evaluation of support units and systems currently used with a view to improving the effectiveness of support, stability and safety of tunnels.

Author: Haile, AT ; Grave, DM ; Sevume, C ; Le Bron, K Date: Dec 1998 This report details a methodology for rational design of tunnel support systems based on a mechanistic evaluation of the interaction between the components of a tunnel support system and a highly discontinuous rock mass structure. This analysis ... Read more
Support technologies to cater for rockbursts and falls of ground in the immediate face area, volume 1.

Author: Daehnk, A ; Acheampong, E ; Reddy, N ; Le Bron, KB ; Haile, AT Date: Mar 2000 The aim of this project is to investigate temporary and face area support systems (with special reference to the use of tendon support). Improved face area support design methodologies are proposed, and a probability analysis is conducted to ... Read more
