FIGS was officially launched

Following the previous approval by the IAEG and the ISRM, the Council of the ISSMGE approved, last October, the Cooperation Agreement for formation of the Federation of the International Geo-Engineering Societies - FIGS. The role of the Federation is to carry out functions for the international geo-engineering community that could not be carried out with the same effectiveness and efficiency by the Members individually. The Federation is founded on the principle that each of the participating associations/societies will retain its identity and autonomy.

The inaugural meeting of FIGS took place in London, on 25 January 2008 (see photo). The activity developed until now was reviewed. The main achievement so far has been to form 7 Joint Technical Committees (JTCs) with members from the 3 societies, which are already working. Another 4 JTCs are now being established. With the formal start of operation of FIGS it is expected that its activities will be significantly increased during 2008.

Following a procedure approved at that meeting, Prof. William van Impe was elected the President of FIGS for 2008-2011.

Research on pillar strength in South Africa

On a recent visit to the Eastern Free State region of South Africa, the ISRM Vice President for Africa Dr Malan stumbled upon this interesting “mushroom” rock formation. This area is known for its beautiful landscape and rock formations created by the erosion of the Clarens formation sandstones and have become a popular alternative tourist destination in South Africa. The base of the mushroom was an approximate rectangular shape reminiscence of a slender pillar with a high width to height ratio. It was a most unfortunate discovery as a rock engineer on holiday does not necessarily want to solve pillar strength problems!

A stability analysis of the feature will be presented in the next issue of the ISRM News Journal. The factor of safety obtained for this “pillar” still appears very large and provided a strong wind does not topple it, visitors should be able to enjoy this interesting formation for many years to come!

Nature's in situ shear test

These photos were taken by our Vice President for North America Prof. Derek Martin, during one of his hiking trips last summer in the rocky mountains south of Banff, Alberta. The hiking trail follows the valley and encounters a relatively recent rock slide. The slide has occurred in thick beds of limestone. As the other photos show nature has a simple way of testing for limiting equilibrium. In the close up slide, a tension crack appears to separate the bed and raises the question: does the tension crack occur first and allow the block to slip, or does the block slip first which creates the tension crack?

Perhaps our members will have an answer?

Water transfer tunnels for the Jinping II hydro-electric power station, China

The largest water tunnels for a hydraulic power station are being constructed in China with overburdens up to 2,500 m (see the geological section). There are four tunnels, each 16.67 km in length, with 60 m spacing between them. Two are 13 m in diameter, excavated using blasting, and the other two are 12.4 m in diameter, excavated using TBMs. They are being excavated in marble, sandstone and slate strata. Construction started in August 2007 and will be finished in 2012.

Australian mining boom creates strong demand for rock mechanics professionals

The past few years have seen growth of up to 29% p.a. in output from Australia’s mining industry. In 2007-08 the “metals” and “other minerals” industries (not including petroleum) are forecast to contribute nearly $67 billion to Australian exports. Mineral commodities, for which export earnings are forecast to increase, include iron ore, gold and nickel.

Although there are currently approximately 110,000 people employed within the industry there is still a significant shortage of skilled workers at all levels in all professions. This shortage is a significant impediment to the further profitability and growth. At an individual company level, some companies have experienced a turnover in staff of up to 25% p.a. The associated dilution in “corporate memory” and decrease in the continuity in the management of minerals projects has been problematical.

The shortage in personnel has also applied to rock mechanics professionals for whom there has been a strong demand from both minerals and civil companies. Hearsay evidence indicates that the shortage has necessitated that inexperienced or unsuitable candidates have been required to take on roles or projects that would once have been filled by more experienced senior professionals. The challenges these demands have placed on members of the rock mechanics community have, over the past few years, resulted in a strong increase in colleagueship between them.

With a forecast demand for up to 70,000 workers in the minerals industry over the next decade, and a strong demand for rock mechanics professionals, the related challenges to the growth of the industry are expected to increase. This growth is however a direct function of the strength of the world economy. As there are considerable downside risks surrounding its short term outlook, associated with the recent weakening in global credit markets, growth may be stymied by any decrease in demand by overseas countries for Australia’s mineral products.

Extra-terrestrial rock mechanics at SINOROCK 2009

Are you unworldly enough to tackle extra-terrestrial rock mechanics?

For almost 50 years now, the ISRM has studied rock mechanics on Earth – but do all the fundamentals that we have developed also apply on the planets?

Wanted: a theoretician to go through the fundamentals of rock mechanics and establish whether they all apply out of this world – and to give a report at the SINOROCK 2009 international ISRM symposium at the University of Hong Kong in May 2009. Hopefully, Newton’s Laws apply. What about poroelasticity? What about the Hoek-Brown failure criterion?!

Volunteers please contact John Hudson at john.a.hudson@gmail.com.

6th International Symposium on Ground Support in Mining & Civil Engineering Construction
An ISRM Regional Symposium

This International Symposium is being organised jointly by the Southern African Institute of Mining and Metallurgy (SAIMM) and the South African National Institute of Rock Engineering (SANIRE). The symposium will take place at the Tablebay Hotel, Cape Town, South Africa, 30 March - 3 April 2008. Previous symposia on this specialist subject have been held in:
• 1983 in Luleå, Sweden
• 1992 in Sudbury, Canada
• 1997 in Lillehammer, Norway
• 1999 in Kalgoorlie, Australia
• 2004 in Perth, Australia

Ground support is used extensively in both civil and mining environments, but commonly there is insufficient interaction between these two disciplines. In both fields significant developments in ground support take place regularly, and miners have much to learn from their civil colleagues and vice versa.

Local technical site visits will be arranged. There will also be post-symposium visits to a deep-level mine and to tunnels and excavations for the Gautrain, the mass transit system that is under construction in the Johannesburg-Pretoria area.
