Following on from an earlier research project to establish the trends in seismicity and rockbursting in South Africa's western Bushveld Complex region, a set of 12 animated training modules was developed for production personnel under SIMRAC Project SIM140301, funded by the Mine Health and Safety Council. The sets were subsequently introduced to training centres in the western and eastern Bushveld Complex (BC). A separate project output created text-based and visual training materials for rock engineering personnel, which were distributed to mines according to their staff complement in the range of Strata Control Officer and levels above.

The project also drafted an audit protocol suitable for a range of different seismic system set-ups, assessing three main aspects: seismic network planning and operation; seismic source quantification; and rockburst analysis and reporting. All nine mines currently operating seismic networks in the BC joined the audit initiative. The final scores range from 60% to 100%, with Impala Platinum's networks and Mine C (name withheld) being the best planned and operated networks among the BC mines. The highest compliance levels are achieved in the needs-based planning of network layout; the procedures to maintain minimum quality standards for seismic source parameters; and periodic reporting to management and production sections.

INTRODUCTION

From detailed analysis of rockbursts in platinum mines of the Bushveld Complex (BC), the factors contributing to seismicity, common geotechnical information gathering, and the data analysis methods implemented on mines, the SIMRAC project SIM100301 (Essrich, Hanekom, and Stankiewicz 2012) suggested methods of improving mining practice, the effective gathering of rock mass-related information, suitable seismic monitoring procedures, and effective training initiatives.
