Gauteng Branch Teaches the Ropes!

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.

New developments

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”.

futed

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.

“Anything less than a conscious decision to the important will lead to a subconscious decision to the unimportant” – Stephan R Cowey

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 (jannie.maritz@up.ac.za). 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

CONFERENCE THEMES

• Geotechnical and financial risk assessment and

management

• 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

• Blasting

• Ventilation

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 publications-acg@uwa.edu.au

ARO

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.

The Chamber of Mines certificates will be phased out on 31 December 2018. These certificates will be replaced by new certificates that will be issued by the QCTO and/or other educational institution. The last entry for new candidates into the system would have been 31 August 2015, but because the assessment tools of the QCTO are not ready this date was postponed until 31 March 2016 for the May 2016 examination.

The last entry for the new candidates will now be 31 August 2016, hopefully the QCTO assessment tools will be ready for the October 2016 examinations as the final entry date cannot be changed.

It must be noted that the final phasing out date of 31 December 2018 for all certificates is final.

 

 

The SANIRE AGM was held on the 27th November 2015 at the Ruimsig Country Club. The new format of the AGM comprised of the formalities in the morning followed by lunch and ended off with a round of golf. The AGM provided an overview of the SANIRE strategy for the next 2-5 years. Recognition to outstanding commitment, contribution and achievement through the various award categories was also presented. The AGM was well attended and will hopefully continue to do so in the future. A special thanks must be given to Carol Hunter for all her hard work in making the AGM possible.

pc1At the AGM held in November 2015, we recognised some of our members for their extraordinary achievements and contributions to our fraternity through the grants of awards in various categories. As Rock Engineers, just doing our jobs, we do not always realise the influence we have on those around us. Through mentoring, we develop the skills of our colleagues and we instil a culture of caring, self-worth, ambition and recognition.

In the workplace as technical specialists, we are responsible for ensuring the safety of thousands of workers through our routine monitoring. Our selfless efforts are not always recognised and typically the areas where we make the largest contributions are celebrated by the industry at events such as MineSafe. However, the efforts of the Rock Engineers and the Rock Engineering Departments are not credited for their interventions which contribute to a safer working environment. As a service department, we do not contribute to the bottom line, but we can contribute strongly through our dedication and involvement. In December, the Principal Inspector of the North-West region issued an instruction for all mines in the Rustenburg area to stop their operations and instructed that all areas be assessed by Rock Engineers to ensure that our workers do not work unsafely or become exposed to an unsafe working environment during the “silly season”. The DMR, therefore, recognises the skills we have in the field of strata control.

There are many factors influencing the behaviour of the workers at the face. We can, however, influence their behaviour through ongoing coaching, in the workplace, at the face. Our contributions can only add value to processes such as the entry examination and TARP, which is aimed at creating a safe working environment. We should realise that our actions will assist in upskilling our workers at the face. We can, therefore, make a difference by caring and sharing. It goes beyond celebrating fall-of-ground fatality free shifts or setting new records.

ebenezerEbenezer Gordon Holder
24 May 1956 - 07 December 2015

I have known Gordon for many years, and worked with him between 1996 and 2002, when I was a member of the Rock Engineering Department at Anglo Platinum at that time. He was the Chief Rock Mechanics Officer. Gordon spent most of his career at Anglo Platinum, and because in the early years there were only a few Rock Engineers employed, he had an intimate knowledge about all the producing shafts.

His time keeping was exemplary, if not extreme – he was always the first to arrive in the office in the mornings and the last to leave in the afternoons. When asked why, his answer was perhaps unsurprising: “My job is my life”.

Another part of Gordon’s work which deserves mentioning was his record keeping and I never saw anyone else doing the same. For underground visits, Gordon had small A6 black books where he wrote what he observed and recommended on any particular day. He would then transfer some important notes from the A6 underground books into his A4 black books which he kept for his daily, planning and various meetings notes. Furthermore, he kept both his book formats bound in clearly labelled volumes. So, if you asked him what he did on any specific day, month and year, Gordon would look into his Register and check which volume and book to open, and he would tell you exactly what he did on that day. All these volumes of books took up most of his vast filing cabinet.

Gordon had very good observation and interpretation skills underground, given his knowledge and long experience. He loved to coach young and upcoming Rock Engineers – like me at that time – and his advice was very valuable. Not only was he a good Rock Engineer, Gordon’s strength was also in his very broad general knowledge regarding mining, engineering, stores management and industrial relations, to mention a few.

Another incredible aspect of Gordon’s life was his ability to speak the Setswana language fluently. He often spoke Setswana with black colleagues in the office or underground and one could see how much they appreciated that.

Gordon left Anglo Platinum in 2009 to spend his time elsewhere; Samancor chrome mines being the last place.

After his sudden passing, Gordon left behind his wife Jenny and his sister Fiona. Gordon’s plans were to retire and move with his wife to the Western Cape where his sister lives. Sadly, Gordon could not fulfil his dream.

Rock Engineering Manager – Impala Platinum

krugerPaul Kruger van der Heever.
25 April 1947 – 22 December 2015

It is with great personal sadness that I informed you that our friend, colleague and associate of Groundwork passed away peacefully this morning after a long and stoic battle against cancer.

Paul worked on dozens of projects for us after we were fortunately enough to secure the services of this immensely capable man in September 2006. He conducted many geological mapping and stress measurement site evaluation projects, as well as assisting with other geotechnical investigations. For those of you who didn’t know Paul well, he was a geologist and chemist by training who then specialised by obtaining the Chamber of Mines Rock Mechanics Certificate, and also obtained a Master’s Degree in Seismology. His desire to acquire knowledge was endless and he was awarded an MBA Cum Laude while working as the manager of Gencor’s Technical Services Department in Klerksdorp in the 1980s.

Paul was also an incredibly active man who played golf regularly off a low handicap and ran numerous long distance races, including Comrades many times. He had a remarkable and active mind and had many interests and hobbies. However, his passion always seemed to be geology. I called him our bionic geologist as he had the ability to see well beyond the rock surface when making his geological assessments. Despite his incredible technical skills, he had the relatively unique ability to present findings to senior management in a manner which they always understood and appreciated. An example of this is the model he built by himself to assist the shaft personnel to better understand the complex geology at Kloof Main Shaft. He did this in his spare time, without compensation, out of his own enthusiasm for the project. He was always keen to share his formidable knowledge to help others grow and develop.

Paul touched the lives of many people and he will be sorely missed. At this time, our thoughts are with his wife Bets, his children, Paul Junior, Lisa and Marissa, and his six grandchildren.

Kind regards, Phil.

The Sixth Slope Stability Symposium was held in Cape Town from the 12th to the 14th of October 2015, hosted by SANIRE in conjunction with SAIMM. The symposium was originally held in Cape Town in 2006 and has subsequently been to Perth (2007), Santiago (2009), Vancouver (2011) and Brisbane (2013). Since it is the only dedicated slope stability conference internationally, it is consistently well attended. While attendance was less than in previous years, as is expected in current times, it still attracted just over 200 delegates, 130 of whom were international. Keynote speakers were Professor Doug Stead from Simon Frasier University, who presented his research on internal failure mechanism during failure, comparing it to current analysis technics; Dr Loren Lorig CEO of Itasca, presented on designing for extreme events; Geogg Beale (Director at Schlumberger Water Services) presented on the importance of surface water management and its impact on slope stability; and Louis Melis (Melis & Du Plessis Consulting Engineers (Pty) Ltd) presented the recent work he has been doing in designing rock fall protection. Fifty-four papers and ten posters were presented and published in a proceedings volume, a selection of which will be published in an upcoming issue of the SAIMM Journal. A slope stability monitoring workshop was presented on the 15th, organised and facilitated by Huw Thomas from the University of the Witwatersrand. Thanks goes out to the organising committee, SAIMM, presenters and the very generous sponsors!

Chair, Organising Committee.

Commissions

Full Name: Deon Louw

Position: Unit Manager – Rock Engineering Beatrix 3#

Company/Organisations: Sibanye Gold

Date and Place of Birth: Born in Bellville, Cape Town, on 4 March 1960

Education: Matriculated at Bothashof, Salisbury (now Harare)

First Job: Learner Official Mining, Buffelsfontein Gold Mine, Genmin

Personal Best Achievement/s: The design and actual early extraction of the Beatrix 3# Shaft pillar

Philosophy of Life: Too much of anything is not good. Live a balanced life.

Favourite Food/Drink: A good Irish whiskey (Here, I ignore my philosophy). I love chicken – braaied or grilled – with Portuguese spice.

Favourite Sport: I work only because my golf is not good enough.

1. How did your career in the mining industry begin and where are you now?

Following the completion of my military service in 1980, I started off at Buffelsfontein Mine as a Learner Official and later became production Shiftboss, mostly at Orangia Shaft. In 1987, a neck injury in rugby forced me to assist the Rock Engineering Dept for 6 months, while I could not go underground. This was the first time that I was really exposed to Rock Engineering and I immediately became very interested in the subject. Shortly after my return to underground, I applied for the position of Strata Control Officer and Joined the RE Dept. I obtained my COM Cert in 1990 and moved to Beatrix mine in the Welkom area in the same year. During the next 10 years, I toured the Welkom Goldfields, working at Oryx Mine, St Helena and back to Beatrix again, working for the same company. (Genmin, Gengold, Gold Fields). In 2002, I joined Brentley, Lucas and Associates, and was based at Bambanani Mine until 2011. It was an interesting 9 years, with Bambanani experiencing serious problems in their orepass systems, and eventually scaling down to a shaft pillar extraction. During this time, I also did a lot of consulting work on smaller diamond mines, as well as at the Afrikander Lease operation in North West. In 2011, I was offered the position of Chief Rock Engineer at Beatrix mine and moved back there, saw the unbundling of Goldfields and the creation of Sibanye Gold, and am still quite happy in my role as Rock Engineer at Beatrix 3#.

 

“Confidence. You need to show confidence”                            “Confidence sells!”

 

2. Why did you choose Rock Engineering?

I was very fortunate to be exposed to RE early in my career and to then be able to make the career change to Rock Engineering. It is probably the most interesting, challenging and exciting discipline in the mining industry. No two days are the same, no two problems are the same, and no two people are the same. Every day, there is something new and you keep on learning and gaining experience every day.

3. Please tell us a bit more about your career journey?

Covered in 1.

4. In your opinion, what are some of the challenges that the fraternity is currently facing?

I think our biggest challenge currently is that our design function is under threat. There is a tendency that we shouldn’t design support to suite, but rather to design for the worst case; if one operation utilises a system, it must be implemented throughout, whether it is relevant or not. It is no longer a case of designing out or reducing the risk in the mining of a block ground, but rather that if there is risk, abandon it. We can only overcome this by educating the prescribers and enlightening them in the principles of Rock Engineering.

5. What are some areas that you believe will become of increasing importance in the near future of the rock engineering discipline?

I believe we will be required and that we need to play a much larger role in the ongoing planning of workings. The expertise is no longer there, as it used to be, and once again, we need to coach and educate.

6. What advice would you offer people aspiring to be in your position?

Confidence. You need to show confidence: when you present a plan, or when you motivate a new support system, mining sequence, whatever. Confidence sells! Even if you yourself are not too confident in what you propose, propose it with confidence.

7. Who is your role model/mentor?

I cannot single out one person. There are too many people that I came into contact with in my career who all contributed in my life, whether big or small. Each person has something to offer which will benefit you in some way.

8. What is the best advice you have ever been given?

It’s a golfing tip – Aim high, don’t set a low target because then you will hit the ball low. And it is the same in life, set your goals high.
