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.
The following presentations were presented on the day during two sessions which were led by Dr Jaco Le Roux and Mr Paul Couto:

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.
Malaysia has been approved as a new national group of the ISRM.
The European Rock Mechanics Symposium – EUROCK 2018 – has been approved as an ISRM Regional Symposium. The conference will take place in Saint Petersburg, Russia, in May 2018.
The Shaoxing International Forum on Rock Mechanics and Engineering Technology has been approved as an ISRM Specialized Conference. The conference will take place in Shaoxing, Zhejiang, China, from 31 October to 1 November 2016.

The official launch of the South African National Institute of Rock Engineering took place at a function held on 6 July 1999 at the Wanderer‟s Club in Johannesburg. At the launch, the out-going Chairman of SANGORM, Dr. Güner Gürtunca, reported on his period of chairmanship from February 1994 to July 1999. His report was followed by an address from SANIRE‟s first president, Dr. Nielen van der Merwe.

There is, of course, evidence of mining in Southern Africa, stretching back a great many centuries, but concentrating for the time being on gold discoveries by Europeans on the Witwatersrand during the nineteenth century, we find many stories of gold finds dating back to long before the official discovery in 1886. Not many of these find support in the written archives, though. A Dutch hunter, Karel Kruger, is purported to have found gold on the Witwatersrand while on an expedition in 1834, and to have taken some samples back to Cape Town. Two years later, on his return to the interior to hunt and follow-up on his gold find, he and most of his party were massacred by tribesmen close to where Potchefstroom stands today.
For a long time now, and more so in recent months, the growing concern about the phasing out of the current Chamber of Mines certificates in Rock Engineering has raised some eyebrows, with the registration cut-off of 2015 and examination deadline of 2018. If was with new flair and urgency that the 2015-17 SANIRE Council (through the FUTURE EDUCATION portfolio) joined forces with the two other disciplines also affected by this decision (MINE VENTILATION SOCIETY & SOCIETY OF MINE SURVEYORS) to meet the Chamber and highlight concerns on closing the registration for candidates at the end of 2015. This fruitful meeting resulted in the re-opening of the registration for 2016 to allow entry into the current process, pending the outcome of a meeting scheduled with the CEO of the Chamber, at which the 2018 deadline will be again discussed.
This meeting yielded an extension of the deadline for both the registration (Aug 2018) and final exam sitting (Oct 2020) for all three disciplines. It was made clear that as this was the third extension granted, this would also be the last. The permission granted then, of course, comes on top of specific barriers that need to be overcome prior to 2020 in order to ensure, firstly, a sustainable solution to a qualification going from 2020 and beyond, and secondly, a seamless transition from the current system to the new.
The development of the new qualification in Rock Engineering will also see some changes to designation(s). In future, the now-known ‘Rock Engineer’ will be called a ‘Geotechnical Engineer’. This is in line with international designations, as currently only South Africa uses the term ‘Rock Engineer’. This will also fit into the understanding in Civil Engineering of applying knowledge and engineering to natural sand and rock environments.
A schematic is presented below to allow a ‘quick pic view’ of the timelines for the phasing out and in of the various “qualifications”.
The registration for the process is open until Dec 2018. This will allow for six (6) more open sittings under the current system. Once the registration process has closed, the candidates in the pipeline have four (4) more attempts available to obtain the certificates, after which the new qualification needs to be completed. People entering the discipline during 2019 and later would need to complete the qualification ensuring a pipeline of qualifications when the Chamber’s current window of opportunity is closed in 2020. This applies to both the strata and rock engineering certificates.
Observer – The Level 3 qualification for Observer in Hard Rock has been registered with the Quality Council for Trades and Occupations (QCTO). This is required by people working as observers in the Hard Rock environments. (*Not indicated in the schematic).
CoM Strata Control Certificate – Three Level 4 qualifications (Strata Control for Hard Rock, Massive Mining, and Coal) has been registered with QCTO, with a fourth qualification (Surface) pending. All strata control officers would need the new qualification for 2021 and beyond.
CoM Rock Engineering Certificate – In order to practise as a geotechnical engineer (pending approval of the proposed legislation changes), one would need to be in possession of the current CoM certificate (either one of the four) obtained at the latest during the 2020 October examination, or be registered at either ECSA or the Natural Science Council (with work experience on the type of mining), or lastly, be in possession of the Level 6 QCTO qualification.
As the Competence certificates from Chamber will be discontinued, the need for legislation updates and reviews are under way. As mentioned in the schematic, the proposed legislation changes will then allow practitioners three options to legally apply their services at a mine. These routes are – registered professional through either the Engineering Council or Natural Science Council, the current CoM certificate, or the new qualification, if and when available.
The advice from Council would be to get yourself into the system, prepare with due diligence and complete the certification as soon as practically possible. If you are planning to wait for the new format of acknowledgement, don’t. If you are planning to pass the last sitting, change your timelines. Never leave your studies to the last minute. Set your goals straight and meet your target. Call is Call.
One of the barriers that would also need to be overcome is that of finding candidates who could assist in the development of the Level 6 qualification and assessment tools. As Chamber has a record of past papers and SANIRE has a well-accepted curriculum and set of learning material, packaging this into the new format shouldn’t be an issue. However, the involvement of so many other entities (SANIRE, CHE, MQA, QCTO, COM) results in long lead times between approvals of various milestones along the way for registration of learnerships.
The second would then obviously be service providers to the candidates for presenting the qualification. As we are led to believe that the process is relatively easy, SANIRE (Future Education) would like to urge potential service provider to get in contact and get their company names on the list, so that when the process of registering the providers starts, they can be informed.
For any enquiries or getting your name on the volunteer list or providers seeking assistance, please contact the portfolio holder Jannie Maritz (email@example.com). The process is related to all levels (Levels 3, 4 and 6 <when these realise>).
28–30 March 2017 | Perth, Western Australia
Underground mining continues to progress at deeper levels and industry is now extracting mineral reserves at depth that previously would have been considered unmineable. Deep mining is a very technical and challenging environment. A high level of understanding and technically sound approaches are essential to satisfactorily deal with the significant geotechnical (from squeezing ground to rockbursts) and logistical (transportation, ventilation) issues of deep and high stress mining, and best practice and innovation need to be implemented.
The Australian Centre for Geomechanics looks forward to hosting the Eighth International Conference on Deep and High Stress Mining in Perth in March 2017. This follows the previous conferences held in Sudbury, 2014; Perth, 2012; Santiago, 2010; Perth, 2007; Quebec City, 2006; Johannesburg, 2004; and Perth, 2002.
ABSTRACTS DUE 4 JULY 2016
• Geotechnical and financial risk assessment and
• Numerical and empirical design and analysis
• Case histories (success stories as well as failures)
• Rock mass response to mining (rockbursts and seismicity, squeezing ground)
• Occupational health and safety
• Ground support
CALL FOR ABSTRACTS
Intending authors are requested to prepare and submit their abstracts before 4 July 2016. Abstracts should be limited to less than 500 words. Abstracts for Deep Mining 2017 can be submitted online at www.deepmining2017.com/authors or via email to firstname.lastname@example.org
Planning for the 50th US Rock Mechanics/Geomechanics Symposium in Houston from 26-29 June 2016 is well underway. Nearly 650 abstracts were accepted for the symposium. The abstracts suggest there will be very strong oral and poster sessions, spanning petroleum, civil, mining, and interdisciplinary topics in rock mechanics and geomechanics. Continuing the trend from the last few years, a very large number of abstracts and sessions revolve around "interdisciplinary" topics that are of interest to civil, mining, and petroleum geomechanics professionals and showcase the unique value of the symposium to ARMA members.
In addition to the strong technical program, ARMA will host six geomechanics-related workshops and two short courses. Workshops will be held on Hydraulic Fracturing, Geomechanics in Unconventionals, Laboratory Geomechanics Testing, Reservoir Engineering Applied to Geothermal, Microseismic Geomechanics, and an ARMA Future Leaders-Student workshop. Short courses will be taught on Shale Gas Geoengineering and Modeling of Coupled-Hydro-Mechanical Deformation and Fracturing.
The Symposium will feature the first ARMA Distinguished Lecture, offered by Richard Goodman. The MTS Lecture will be presented by Peter Kaiser; William Ellsworth, Jean-Claude Roegiers, and Charles Fairhurst will be featured in keynote lectures. Technical tours will highlight Houston's petroleum history (tours to Spindletop and the Ocean Star Offshore Drilling Rig) and geology (tour of active faults in the Houston area).
The symposium will be held at the Westin Galleria Hotel and Conference Center. Holding the meeting in Houston will allow a larger number of petroleum-related geomechanics professionals to attend and broaden the interaction between the rock mechanics/ geomechanics disciplines and industries.
