Rock Bursts

Deep mine layout design criteria to reduce seismicity
Criteria for preconditioning at varying stoping widths
Following the completion of the research projects GAP030 and GAP336 certain mines have tried to implement the technique in faceburst-prone high stoping width areas but unfortunately these attempts were claimed to be unsatisfactory. The
Criteria - small span small pillar concept in deep mines
De Frey in his report of mine design alternatives for the DEEPMINE project found that the small span small pillar (SSSP) concept, as a mining method for deep mines, from a rock engineering point of view, had certain positive advantages.
Calibration of intergration-ready numerical models to real seismic data
The project is a continuation of GAP603: Fundamental Aspects of the Integration of Seismic Monitoring with Numerical Modelling. It was decided that the parallel study of two integrated models as different as MAP3Di and IDRM, the
Audit of project GAP 017 2
Following a request conveyed in a fax dated 25 November 1996 from Mr DP Allen, the secretary to SIMGAP, a proposal was submitted to the Advisory Group early in December. The project title given in the proposal was: Audit/ review
Audit of project GAP 017
The GAP017 project focused directly on predicting the time and place of impending rockbursts, on three time scales that are called alert, alarm and scram. The project aimed at using improved seismic systems, analysis methods and
Assessment of seismic risk in Bushveld complex platinum mines
The objective of this project was to assess the seismic risk in the Bushveld Complex platinum mines and to provide guidelines for regional and local support in areas where the seismic risk is considered to be high. In order to achieve this
Application of indirect stress measurement techniques
Reliable values of in situ stress are essential for the valid modelling of mine layouts.  Available non-strain gauge methods are reviewed as potential practical techniques for South African mines.  From this review it is
Accounting for the variability in rock engineering design
Conditions in nature are very variable.  Man-made items are also variable, although less so, since they are usually made according to a design with materials whose properties are known.  These two statements are relevant with
Accessibility of active fault planes for controlled activation
