37th Technical Evening, 30 June
WITS School of Mining
New Concept Mining
A very successful technical evening was held by SANIRE’s Gauteng Branch on 30 June 2016 at WITS University’s Digital Mine facility, in conjunction with New Concept Mining. Prof Fred Cawood and his team of postgraduate students facilitated the event in the superb mine design laboratory, which was put together through sponsorship from Anglo American. Two talks were presented; the first talk was by WITS postgrad student, Prince Mulenga (SRK) on coal squat pillar design using numerical modelling, followed by Prof Cawood’s overview of the WITS digital mine facility and of the state of the art in mining technology, as well as of history and a vision for the future.
A Strata Control Mini Symposium was organised and held by the SANIRE Free State Branch at Diggers Inn in Welkom on the 9th June 2016. The day was opened with a keynote address from the SANIRE President, Mr Michael Du Plessis.

How did your career in the mining industry begin and where are you now?
I joined the mine seismology group at IMS after completing an MSc (Physics) at the Nelson Mandela Metropolitan University. I have been involved in providing routine seismological services to the mining industry since 2012, and I was appointed as manager of the South African Seismological Services Group in 2015. During the past two years, I have also been responsible for the development of numerical modelling software.
A change so unexpected, and a development never known before, followed from the discovery in 1886 of the greatest gold mines of all history, ancient and modern. From 1886 (until 1940), the story of South Africa is the story of gold – C.W. de Kiewiet, 1941. The discovery of gold on the Witwatersrand in 1886 was a turning point in South African history. Far more than diamonds, this led South Africa from an agricultural society to become the largest gold-producer in the world. Gold increased trade between South Africa and the rest of the world. For the main trading nations, i.e. the Europe and the United States, gold was of value because their currencies were backed by gold. This was known as the gold standard. Under the gold standard, these countries had to keep gold in a bank vault to the value of the currency they issued. For example, if the government of a country wanted to print more money, it had to buy gold to back that money. If that country did not produce gold itself, it had to import gold from another country. Under the gold standard, the price of gold was fixed internationally. It was kept low as this benefited nations in Europe, as well as the United States, amongst others. These strong nations did not produce gold and had to buy it from elsewhere to back their own currency. In the 1930s, many countries abandoned the gold standard. The effect that this had on the South African economy will be examined later on in this feature.

My wife, Angelique, and I do tandem road racing as a means to keep fit and spend time together. However, for us to compete, we need to make sure that we can operate as a functional team. As it is difficult to communicate with one another when racing, it is important to know each other’s strengths, weaknesses and limits.
Dates: 02-07 October 2017
Venue: Cape Town Convention Centre, Cape Town, South Africa
SANIRE Gauteng Bench’s 2015 year end function taught about 20 SANIRE members “the ropes” at the CSIR’s Rope Testing facility, located in Sunnyside, Johannesburg.
Globally, 2015 was the warmest year on record, with world temperatures exceeding the long-term average based on documented measurements taken since 1880. The previous record year was 2014, and 2010 before that.

Supported by scientific evidence suggesting a link to greenhouse gases in the atmosphere, climate change officially became the subject of international negotiations almost twenty-five years ago – the first agreement to co-operate dates back to 1992 in Rio de Janeiro. Between then and now, the world has generated almost as much carbon as it did during the preceding century.
