This year started off with a bang. On most of the mines, the DMR instructed that certified Rock Engineers should conduct extensive audits of all working places. This created a new role profile of a qualified Rock Engineer – “Auditor”. As a result, we had little time to do anything else. Unfortunately, our work does not only revolve around keeping the DMR happy. We also have to ensure that systems, strategies and other critical areas of our work requirements, which could impinge on the safety of mine workers, are upheld. As a result, we manage the various challenges and crises as well as drive other critical projects, irrespective of the time constraints. I have, however, come to realise that all crises are cyclic and that the end of one challenge will lead to the next.
‘Rock Mechanics for Africa’
Dates: 02-07 October 2017
Venue: Cape Town Convention Centre, Cape Town, South Africa
The 2017 ISRM International Rock Mechanics Symposium is to be held in Cape Town. The conference theme is “Rock Mechanics for Africa”.
Approximately 170 abstracts were received, covering a wide range of topics including slope stability, underground excavation stability, ground support, rock mechanics data, testing methods, instrumentation and monitoring, mine seismicity and rockbursts, and numerical modelling. Over 100 papers have been received and are in the refereeing process.
A new ISRM Online Lecture is available for viewing or downloading on the ISRM website (www.isrm.net): 17th ISRM Online lecture: Prof. Charles Fairhurst – “Why Rock Mechanics and Rock Engineering”

A magnitude 6.5 earthquake struck central Botswana on Monday, 3 April 2017 at 7h40pm, the largest to occur on this con-tinent in 11 years. The location was unusual as most large tectonic quakes in southern Africa are closely associated with the East African Rift System, an extension failure zone stretching from Djibouti by the Red Sea all the way to southern Mozambique. The key words here are ‘most tectonic’: the most seismically active regions in Africa are the gold mining dis-tricts along the edge of the Witwatersrand Basin, but these events are associated with mining and not with plate tectonics.
