  • Open Journal System

    DOAJThe SAIMM has adopted the Open Journal System (OJS) with the objective of optimizing the management of the paper reviewing process for the Journal.

    Paper submissions will no longer be accepted via the SAIMM Journal submission form on the SAIMM website. Only papers that are currently in the system will follow the existing reviewing process.

    You can now submit manuscripts and peer reviews online. The OJS assists you with every step of the reviewing process. Authors can also check the status of their papers online and referees will receive automated reminders for their reviews.

  • Climate change: the impact on the mining sector

    There has recently been a lot of talk about global warming and its impact on weather patterns, i.e. climate change. A keynote address at the recent Infacon conference in Cape Town focused on climate change. Some people believe that this is all a lot of hype. Others (myself included), like the keynote speaker, believe that there is some evidence pointing

SANCOT - The South African National Committee on Tunnelling

SANCOT was formed in 1973 and is a founding member of the International Tunnelling Association which was itself formed in 1974. The creation of SANCOT came about as a result of the extensive infrastructure development taking place in South Africa in the late 1960's and foreseen in the decades ahead. Schemes such as the Orange River Project, Ruacana Hydropower Scheme and Hex River railway tunnel attracted a number of overseas consultants and stimulated local engineering expertise.

The TUNCON 1970 conference which followed was well supported and the organising committee saw the need to set up an umbrella organisation to cover the interests of tunnel owners, designers, researchers, professional specialists, contractors and equipment suppliers. This culminated in the establishment of SANCOT in 1973 with Alec Wilson as the first Chairperson, who then represented SANCOT at the inaugural meeting of the newly formed International Tunnelling Association in Oslo in 1974. Since then SANCOT has been represented at every ITA General Assembly, except one in Prague.

In 2003 there was a significant decrease in Civil Engineering tunnelling in South Africa and SANCOT was reformed as a committee of the SAIMM. The committee is now an interest group consisting of volunteers who meet regularly to collate information on both Civil and Mining tunnelling in South African and to hold conferences, site visits and colloquia.

The South African National Council on Tunnelling (SANCOT) makes an annual award, namely the Alec Wilson Memorial Award for the best paper on Underground Construction, to the author(s) of the best paper concerned with the technology of underground construction published in any South African journal or to any paper by a South African journal or to any paper by a South African author in overseas journals, or in any conference proceedings.
The Award was initially instituted by SANCOT in 1984 in order to encourage South African citizens and residents to submit technical papers on tunnelling matters both for local conferences and publications and overseas events.

Judging Criteria
The criteria for judging by the panel are originality, interest value, quality of presentation, clarity, information content and the contribution of the paper towards the advancement of the technology of underground construction.
Should no paper published be considered of sufficient merit, no award is made.
The award may be divided between the authors of papers judged of equal merit. If more than one paper is considered to be of exceptional merit, the runner-up may be carried forward for consideration together with nominations for the following year.
The Judging Panel elected by SANCOT Exco, consists of three persons, each of whom represents one of the three main 'constituencies' within SANCOT, namely Tunnel Designers, Tunnel Contractors and Suppliers and Tunnel Owners. This enables a balanced paper review to be undertaken.

Photo_Alec_WilsonThe late Alec Wilson was one of South Africa's foremost Tunnel Engineers. He was born in Cape Town in 1926 and grew up in the Eastern Cape Province of South Africa. He obtained his Civil Engineering degree at the University of Witwatersrand, Johannesburg and joined the South African Department of Water Affairs. In 1964 he became a partner in the Consulting Engineers Keeve Steyn and Partners, remaining with them throughout his career.
He was heavily involved in the Orange-Fish River Scheme and continued his career in tunnelling and rock mechanics. He was chairperson of Tuncon '70, one of the first major international conferences to be held in South Africa in 1970. Following that conference he was instrumental in the formation of SANCOT in 1973, being it's Chairperson until 1976 and subsequently assisted in the formation of the International Tunnelling Association in 1974.
He was involved in many tunnelling conferences and became well known as a mediator and arbitrator. He advised on a number of aspects of the Lesotho Highlands Water Project. After his death in 1992, it was unanimously decided by SANCOT Exco in June 1993 that, as a lasting tribute to a fine engineer, the Annual SANCOT Award should be presented henceforth in his memory.
