Last issue of the News Journal is now being distributed

Since the last Issue of this ISRM News Journal, there has been a change of the ISRM Board, from the old 2003-2007 Board to the new 2007-2011 Board — which has occasioned an associated change in Editorship of the Journal. Now the News Journal is edited by myself, with assistance from Nuno Grossman, Luis Lamas and Susana Guerra, all from the LNEC in Lisbon.

Each year, there will be one hard copy ISRM News Journal and several electronic ISRM Newsletters. All of them can be viewed on the ISRM website.

The Board‘s main thrust during our tenure in 2007-2011 is "Modernisation of the ISRM". We are determined to enhance the benefits to Members and we are vigorously implementing a variety of improvements, including:

  • expanding the website,
  • making more literature available,
  • identifying the major technical issues,
  • focussing the content of the ISRM Interna-tional Symposia,
  • increasing the recognition of Members‘ achievements through an increase in the prizes available,
  • proposing Lecture Tours and access to educational material,
  • increasing interaction with other Societies, &
  • better communication with Members.

We do hope that you will enjoy this new format ISRM News Journal and that you will stay in touch! To download this and previous numbers of the News Journal follow the link: https://www.isrm.net/gca/index.php?id=206

Survey on the ISRM - preliminary summary of the results

The results from the recent survey of members have been analysed. They provide us with the first insight into who our members are and what they would like from their Society. The survey comprised 34 questions, 26 of which were for members, the others being for non-members.

A total of 396 survey responses were received from members which represents a 7.5% response rate. The members were asked to answer 23 multiple choice and 3 short answer questions. A total of 1716 comments were obtained for the latter questions.

The responses, and the implications of them for the future direction of the Society, are now being reviewed by the Board. We will issue our members with these details when the review is completed. However in the meantime here is a snapshot of some of the results.

  • Europe and South America, with the greatest and least numbers of members respectively, generated the greatest and least numbers of responses respectively. This result was expected. However, while approximately 16% of members from South America completed the survey, only 5% of members from Europe did so.
  • Over 55% of the respondents are aged between 30 and 50 with the age distribution being skewed significantly towards the older ages. Most respondents are highly experienced with over 61% having worked in rock mechanics for over 11 years and 32% having greater than 20 years of experience.
  • 93% of the respondents were male. The disproportionate number of men is not unexpected; it reflects the general international statistics indicating a lack of woman in engineering and geo-sciences.
  • 78% of respondents have a postgraduate qualification (i.e. a qualification other than their first degree).
  • 93% of the responders carry out projects in civil construction and tunnelling; areas traditionally associated with rock mechanics.
  • 43% of the projects carried out by respondents involve the mining industry. A smaller, yet still significant proportion (3%) of projects, are involved within the nuclear and energy generation industries.
  • The most significant reasons why members join and remain in the Society are:
    - The ability to establish contacts within the discipline.
    - The ability to obtain benefits not available to non-members.
    - Members find it useful to participate in ISRM activities.

A more detailed analysis will be posted online in the form of a report and the conclusions will help shape the future initiatives of the society.

Crazy Horse memorial

Under the heading of ‘Interesting Rock Engineering Project Objectives’ is the Crazy Horse Memorial, located in the Black Hills of South Dakota, USA. It is the world’s largest mountain carving in progress. When completed, it will be 641 feet long and 563 feet high. Sculptor Korczak Ziolkowski began this undertaking in 1948 at the invitation of Lakota Chief Henry Standing Bear, who wanted a monument to honor the warrior and hero, Crazy Horse. Work on the mountain carving continues year-round, with hundreds of tons of rock being removed weekly. Shaping of the colossal horse’s head is now the main focus of the work and extends 300 feet below the top of the sculpture – see photos.

A visit is definitely recommended. For more information visit the website at www.crazyhorsememorial.org.

Successful San Francisco 2008 Symposium

Joint 42nd US Rock Mechanics Symposium and 2nd US-Canada Rock Mechanics Symposium, Sponsored by ARMA and CARMA, 29 June – 2 July 2008.

This Symposium was a great success having about 350 registrants and an excellent technical programme. It was held in the Westin Hotel on 3rd Street in downtown San Francisco. The Chair of the Organising Committee was Sarah Wilson of Jacobs Associates who will be succeeding David Yale of ExxonMobil Upstream Research as the new President of ARMA (American Rock Mechanics Association). Peter Smeallie, ARMA’s Executive Director, was the Symposium Co-ordinator.

The Symposium was preceded by Short Courses, Workshops and a Field Trip. Highlights were the Keynote talks, which included one by Kevin Lesko on the proposed DUSEL (Deep Underground Science and Engineering Laboratory at Homestake Mine in the USA) and another by Mark Zoback on scientific drilling into the San Andreas Fault. A particularly advantageous aspect of these US Symposia is the strict adherence to the timing of presentations during the parallel sessions, so that one can change sessions and be sure to attend selected talks, because they are exactly on time. At the Symposium Banquet, the first 10 ARMA Fellows were inducted – chosen by their distinguished service to ARMA and the rock mechanics community.

John Hudson, President of ISRM and a Life Member of ARMA, attended not only the Symposium but also a portion of the associated ARMA Board Meeting where useful discussions were held on enhancing the ARMA-ISRM interaction.

Mine Closure Commission report now available


Members of the commission on one of several underground inspections of old mines


Commission members study mine plans prior to an underground inspection


A sinkhole resulting from the collapse of old mine workings


Some commission members on an inspection of the ancient mining underneath the city of Paris

The final report of the Commission on Mine Closure under the presidency of Christophe Didier of INERIS, France, has now been completed and is available to members of the ISRM. For download click here.

Several countries have a legacy of old, closed mines that now pose certain problems and in extreme cases, even danger to the public. The commission was set up to study the problem in international context and to propose a uniform method of handling the problem.

This work concentrated on the physical rock related aspects of mine closure and did not for instance include the social aspects in depth. The main problems arising from the closed mines relate to time dependant failure of old pillars or even overburdens spanning old works, resulting in surface subsidence.

The subsidence problems can be severe in certain cases, like the unexpected and sudden appearance of sinkholes on the surface. In other cases, the subsidence occurs over large areas over long periods of time and is easier to manage.

The report describes the mine closure situation in several countries, including ones not commonly associated with problems arising from the failure of abandoned mines like Japan and Korea. It is a reference work that describes different methods of handling the problem in different countries, including the legislative aspects.

Direct and indirect monitoring methods are described, as are technical methods of stabilizing old workings or protecting the public against the reopening of old mine shafts.

The report recommends a comprehensive risk management approach to handle the problem. Differentiation is made between gradual subsidence and sudden events. Depending on the nature of the expected effects, different reactions can be identified, ranging from doing nothing except to handle minor effects as they appear, to back filling old mines or even evacuation of villages in extreme cases.

The commission is currently in dialogue with the ISRM Board to extend the work of the first report, mainly to include countries that did not participate in the first commission.

The commission members contributing to the compilation of the final report were:

  • C. Didier, INERIS, France
  • J.N. Van der Merwe, University of Pretoria, RSA
  • Ö. Aydan, Tokaï University, Japan
  • M. Bétournay, CANMET, Canada
  • J.P. Josien, Geoderis, France 
  • A. Kotyrba, GIG, Poland 
  • M. Mainz, Heitfeld-Schetelig GmbH, Germany
