SMMH CONFERENCE 2009
STRUCTURES FOR
MINING AND
RELATED MATERIALS
HANDLING (SMMH)
CONFERENCE
A BRIEF INTRODUCTION
By Dr Hennie de Clercq,
Executive Director, SAISC
It follows logically that South Africa
should be the appropriate venue for
what will be, as far as we can
establish, the first conference in the
world dedicated entirely to structures
for the mining industry. This
conference, entitled ‘Structures for
mining and related materials
handling’ will happen at Sun City on
10 and 11 November 2009.
10 Steel Construction Vol. 33 No. 4 July 2009
South Africans used to claim quite often and proudly: “we’re the world leaders in
mining”. For various reasons we have become more modest with time, and that
boast is hardly heard these days. But fact is that there are aspects of mining in
which we really excel.
One of these subjects is the design and construction of structures for the mining
industry. People may be surprised to know how many structures there are on a
typical mine: bunkers and other structures underground, a major construction to
support the guides for the conveyances (lifts) going up and down the shaft, the
headgear, conveyors, silos and bunkers aboveground, and huge structures supporting
the plant for processing the ore. So big is the demand for mining-related
structures that it was the major impetus behind the development of a steel
construction industry in South Africa, and to this day the mining industry is a major
client of steelwork contractors in this country.
An aspect of mining-related structures in which South Africans have developed
special skills is the design of such structures. Proof of the leadership attained by
local engineers operating in the field is that a committee of the SA Institute of Steel
Construction compiled the first code of practice for the design of structures for
mining. This standard has been published by the SA Bureau of Standards as SANS
10208: Design of structures for the mining industry. It is widely acknowledged as
the leading standard in the world and is used from North America to the Antipodes.
It follows logically that South Africa should be the appropriate venue for what will
be, as far as we can establish, the first conference in the world dedicated entirely
to structures for the mining industry. This conference, entitled ‘Structures for
mining and related materials handling’ will happen at Sun City on 10 and 11
November 2009.
The speakers at the conference will come from a number of countries, stretching
from Canada to Australia, but with a strong South African presence. The topics will
cover all aspects of mining-related structures, from design and construction
through to maintenance and counteracting deterioration – a major issue in the
aggressive environment, from corrosion to physical impact and abuse, that most
mining structures experience. Some of the papers at the conference will serve to
clarify issues that have been the subject of controversy among engineers in the field
for some time, while others will introduce new and exciting concepts.
The day prior to the conference will be dedicated to a workshop on SANS 10208
and promises to be of major educational value to young and experienced engineers
alike. On the day following the conference delegates will have the opportunity to
visit mines in the Rustenburg area, which include some of the most state-of-theart
mining-related structures that can be seen anywhere.
We expect delegates to come from all over the world where there are mines, or
where there are companies dedicated to the planning and development of mines
are situated. There is no doubt in our mind that no company who wishes to claim
that they are at the forefront of the mining industry can ill afford to miss the
conference.
The conference should serve to stimulate new thought and development in the field
of the design, construction and maintenance of structures for the mining industry.
A likely outcome is that researchers will recognise this field as one in which a lot
of work still remains to be done. The result can be a period of accelerated development
in the field, leading to more economical structures in the future.
