In November 2015, the COM metalliferous practical for the platinum industry was hosted by the SANIRE Eastern Bushveld Branch at Ivanplats Mine, Mokopane Office. A total of 22 candidates attempted the practical of which 18 attempted the portfolio section, 17 the conventional section, and 11 the bord and pillar section. Overall, it was a successful day and I (Adam Cooper) would like to thank the Ivanplats staff for assisting with the venue arrangements; the Eastern Bushveld Committee for assistance in setting the exams, and especially Andre Esterhuizen for his contribution with respect to candidate applications, and the examiners for their commitment, time and effort.

I would like to congratulate Tati Bantu on obtaining the COM Rock Mechanics Certificate, as well the following people for outstanding achievement in specific sections of the practical examination:

  • Craig Slement – Portfolio
  • Tati Bantu – Portfolio
  • Obed Masinge – Conventional
  • Gordon Rabey – Conventional + Bord and Pillar
  • Omberai Mandingaisa – Bord and Pillar

pc1We are yet again entering difficult times in the mining industry. The commodity prices are low, the Department of Mineral Resources are relentless at issuing stoppages for non-compliance and companies are forced to restructure. Nevertheless, we as a fraternity endeavour to promote safety and cost saving initiatives to ensure that companies are less vulnerable to these external factors.

SANIRE as an institute can however not function without its members. We require active participation at all levels. As practitioners we are seen as an integral part of ensuring safety on our mines, albeit as policing function. However, in the absence of research facilities, mining groups and support manufacturers have taken the initiative to develop new technologies, leading practices or design methodologies. Although we as a technical discipline are not always recognised for our contributions, the mining industry is dependent on our actions in the workplace as well as our safety interventions which lead to new best practice initiatives. In challenging times we have the ability to do extraordinary things. As SANIRE Members and as Rock Engineers we need to brand ourselves and our discipline so that we can create a legacy.

In July 2015 a new SANIRE council was elected in vision of our 2020 strategy. Several additional portfolios were added. Our 5-year vision caters for changes in the legislation, the future of the Rock Engineering Certification and the needs of our members. The detail of the various portfolios will be presented at the AGM on 27 November 2015.

The yearly function was host on the 24 July 2015 at the Red Barn Farm in Dullstroom. The event was well attended with approximately 75 people attending.

The day started off at the crack of dawn with temperatures hovering around 10 degrees and slightly overcast. This was fantastic weather for fly fishing. After a couple of old brown sherries to warm everyone up all the attendees headed out to one of four dams. The dams were sponsored by suppliers at R 3 000 per dam. SANIRE then utilised this sponsorship to stock the dams to the value of R 3 000 per dam. The dams were stocked with Rainbow trout, Brown trout and Golden trout all ranging in sizes. This was done for competitive reasons.

The competition commenced at 06:00 whereby it ended just before lunch 13:00. The competition was based on a few categories.

  1. The smallest fish of the day
  2. The largest fish of the day
  3. Golden trout (each dam had one Golden trout in it. If the Golden trout was caught then the winner would get the main prize for the dam sponsored by the suppliers)
  4. Brown trout (each dam had five Brown trout in it. If the Brown trout was caught then the winner would get a prize for the dam sponsored by the suppliers)

The winners were as follows:
