Rock Bursts

Rockburst site response critera for support design
Rockbursts are a major hazard in South African deep-level gold mines. The severity of damage due to a seismicevent often varies greatly over small distances. The goal of this project is to discover the reasons for this variation
Review of past research areas Seismology Mine Layout Design
Relationship between ERR and seismic energy release
The primary objective of the research was to develop and test modelled system stiffness methodologies and to undertake comparative analyses with seismic energy release for different geotechnical areas. From this objective, the results of
Reduction of seismicity through improved design of layouts
Realistic dynamic testing of stope face support systems
The submitted proposal for the GAP 818 project was formally approved during the first week of May 2001.The objectives of the proposed programme were, broadly, to examine possible ways of preventing the collapse of fractured rock from the
Quantification of seismic hazard from seismic events in mines
1. Two different techniques for seismic hazard assessment in mines were developed. (See APPENDIX A). 2. A test version of the software (Version 0, written in a MATLAB environment) was developed. 3. The procedures and program code
Proactive approaches to rockmass stability and control
This project had three objectives.  The first two objectives were to investigate further and, if possible, implement some findings of the fundamental research project GAP601a: tap-tests and panel sequencing.  The third objective
Predicting goafing by micro-seismic monitoring techniques
The objective of this research project is the investigation of the association of electromagnetic emissions with rock failure. The possible presence of electromagnetic emissions as a result of material or rock failure have tremendous
