Valedictory Message from Professor John A Hudson, ISRM President, 2007–2011

My four-year tenure as ISRM President began at the end of the ISRM Lisbon Congress in 2007 and will finish at the end of the ISRM Beijing Congress, i.e., at about 18.00 on Friday 21 October in 2011. So, I am saying goodbye now through this Newsletter—which is the last during my Presidential period.

It was an honour to have been voted into the Presidential position and I hope that, together with the 2007–2011 ISRM Board, I have served you all well. My theme was ‘modernisation’ and we have indeed implemented almost 30 initiatives over the four years, including

  • the launch of the ISRM Virtual Library hosted at www.OnePetro.org,
  • the creation of ISRM Fellows,
  • the introduction of the ISRM Annual Lecture,
  • running ISRM Lecture Tours and ISRM Field Trips,
  • ensuring that the ISRM Commissions are productive, and
  • organising the ISRM 50-year Anniversary celebrations,

the full list being given on page 6 of the 2010 ISRM News Journal.

One needs a great deal of help to achieve all these goals and I wish to especially acknowledge the ISRM Board members for their inspiration, resourcefulness and support in the generation and implementation of the initiatives. Additionally, the ISRM Secretariat headed by Dr Luis Lamas has provided invaluable advice, assistance and hard work over the four years.

Finally, I should like to assure all ISRM members that my successor, Professor Xia-Ting Feng of the Institute of Rock and Soil Mechanics, Chinese Academy of Sciences, will provide exemplary ISRM Presidential leadership for the next four-year period.

With the joint efforts of ISRM NGs for China and Singapore, as well as the ISRM2011 International Advisory Committee, International Scientific Committee and the Organizing Committee, the preparation of the Congress has been nearly completed.

Seven organizing committee meetings have been held since the kick-off one at the ARMS2006 in Singapore. Under the organizing committee, seven working groups have been established, including Working Groups for General Guidance, Finance, Business Reception, Liaison, Documentation & Publicity, Technical Visit and Publication. The last organizing committee meeting was held on Sept. 24, 2011.

So far, the venue, the technical program and the program of ISRM 50th Anniversary Celebration have been determined. The Final Program is in the process of finalization and will be published soon. As of Sept.13, 2011, 450 representatives from 45 countries and regions have registered online, including VIPs, members, non-members, students, exhibitors, accompanying persons. Considering that the registration system is continuously updated, the number of registrants may exceed 1000. The routes of the Post-Congress Technical Visits have been determined. “you & me (the song of 26th Olympic Game in Beijing)” will be the song offered to the next host country.

The logo of ISRM and the logo of the congress will be used onto rock pieces taken from the Three Gorges Dam site which will be the souvenirs of ISRM2011.

Emblems with the Logo of the 50-year Anniversary of the funding of ISRM is under producing in Beijing.

There will be 15 keynote/Muller Award/Rocha Award speakers, and their topics have been submitted. 384 papers from 48 countries and regions have been received. Taylor & Francis Group will publish one volume of hardcopy proceedings containing full papers of all keynote lectures, Muller lecture, Rocha Medal lecture, and 2-page extended abstract of other papers. Full papers will be contained in a CD-ROM. The cover of the Proceedings has been finalized as the follows. For more information, please visit the website of the congress: http://www.isrm2011.com.

The ISRM2011, a milestone of the development of rock mechanics discipline, will be the summary of the past development of international rock mechanics and the forecast of the future development of international rock mechanics. On behalf of the ISRM2011 Organizing Committee, I deeply thank the support of the ISRM, the ISRM National Groups, the authors as well as those who have made unselfish contributions.

Networking among Underground Research Laboratories is for a New ISRM Commission, 2011-2015

The new ISRM Commission is to be launched at Workshop WS5 on 17 October 2011, associated with the Beijing Congress.

All of you are welcomed to attend, participate, and contribute to WS5 on Monday 17 October 2011, right before the technical sessions of the Congress during 18-21 October at Beijing. We will have lectures and discussion/updates to address the needs and logistics of the initiative for a worldwide networking effort among Underground Research Laboratories (URLs). It will be an informal and informative gathering during a very busy day with concurrent short courses, workshops, commissions, and executive meetings. You can certainly drop in for the WS5 lectures and topical discussions and provide your inputs. Even if you have schedule conflicts, we welcome your inputs for the new Commission scope and contributions to the Workshop Proceeding which will be published in an ISRM Book series. Please feel free to contact Joe Wang jswang@lbl.gov for any details. We appreciate your indications and considerations for availabilities to participate in the workshop, to help in formulating the Commission, and to indicate your interests.

The New URL Networking Commission concept is a relatively recent development, endorsed by John A. Hudson and Xia-Ting Feng, our current and incoming Presidents. You are invited to provide inputs to the Commission scope and to nominate potential Commissioners for consideration by John Hudson and Xia-Ting Feng at the Beijing Congress. We are seeking supports from regional and national groups, from ISRM community at large, and from other related fields.

As indicated below, and to be updated on the Congress web site (http://www.isrm2011.com/upload/shortcourse/WS5.pdf), the WS5 agenda has 5 technical sessions to cover 10 topics that are listed in the original workshop announcement. In the morning sessions, we will cover rock mechanics challenges in deep facilities, deep underground laboratories primarily for physics searches, and URLs designated for radioactive waste assessment. We then have afternoon sessions on site characterization, couple process testing, and inter-disciplinary studies. We will have both a pre-commission briefing at the beginning of first session, and a last session on discussions of initiatives to kick off the new Commission. The Workshop Proceedings with preprints, presentations, and proposals files hyperlinked will be periodically updated on http://dl.dropbox.com/u/7798101/URL-NetworkPPP/TemperateISRM2011.doc.

We are looking forward to meeting you at the Workshop, throughout the Congress, and to receiving your indications of interests and inputs in the months and years to come. The World Network of URLs and a call for integration by Professor Charles Fairhurst at the Deep Underground Science and Engineering Laboratory (DUSEL) Research Association 2010 meeting are illustrated below.

Don’t Take Risks: Consider Mining Geotechnics

Article by Dr Tony Meyers
Vice President (Australasia), ISRM
Principal, Rocktest Consulting, Australia.
Published by Quarries and Mines 2012 http://www.quarriesandmines.co.uk/.

This century has seen, and will continue to see, significant changes in the size and operation of pits throughout the world. Contributing to these changes has been the increasing demand for minerals as populations increase. Over the same period there has been a significant reduction in the rate at which many mineral resources are being discovered, especially at shallow depths. When they are discovered, alternate land use requirements and environmental pressures often made it difficult to convert the resources into reserves. These issues have been fundamental drivers for existing and proposed pits going deeper. New technologies and techniques can make doing so cost effective. However, going deeper can introduce new geotechnical issues for operators. Historically, these issues may only have been considered when a pit was initially designed and/or if pit wall instability occurred. However, in the past decade, increasingly regulated safety requirements are forcing operators to take an ongoing risk based approach to pit wall design and management. In addition, financial pressures have strengthened the link between the economics of a mining operation and the geotechnical risks associated with it. This article considers some of the geotechnical issues an operator must consider to address these challenges.


 

The Furnas Type II Stress Measurement Cell: a recent high-tech development in the South American region

The year 2010 the Young Members’ Presidential Group was formed by initiative of the actual ISRM Board. One of the functions of these members is to diffuse a recent high-tech development in rock mechanics.

Ludger Suarez-Burgoa, from the South American Region, present an interesting history, one that was built in silence but with perseverance; it is the history of Dr João Luiz Armelin and his assistants, supported by a thriving state company, which developed the first South American stress measurement cell for rock mass: the Furnas Type II Stress Measurement Cell.

The Furnas Type II Stress Measurement Cell, is a cell that adopted the overcoring concept to measure in a point the in-situ stress tensor in the rock mass, it was developed in around 15 years. The visits of ISRM experts to South America, 35 years ago, infuse young engineers to the great world of rock mechanics; therefore today, one can present this high-tech development for South America.
