Welcome to Beijing

The ISRM 12th International Congress on Rock Mechanics, jointly organized by the ISRM national groups for China and Singapore, will be held in October 18-21, 2011 in Beijing, China. The congress venue is the China National Convention Center (CNCC), right next to Bird’s Nest and once served as the main press center and international broadcasting location of the 29th Olympic Games in 2008.

With a theme of "Harmonising Rock Mechanics and the Environment", the ISRM 2011 congress emphasizes the critical roles of rock mechanics and rock engineering in sustainable development and environment preservation. The 4-day technical event will serve as a platform where novel theories, technologies and ideas will collide and spark. In addition to the 4-day technical program,workshops, short courses, technical visits, exhibitions and social programs will be organised, meetings and functions of ISRM Board, council and commissions and other ISRM related activities will also take place in conjunction with the congress. Most importantly, the ISRM will celebrate her 50th anniversary during the congress.

Seven organizing committee meetings have been held, following the kick-off meeting in Singapore on November 10, 2006. Great efforts have been devoted into the preparation of the congress, including fund raising, selection of congress venue, website construction, promotion and advertisement, invitation of keynote speakers, call for papers, paper review and edition, program arrangement, and selection of technical tours, etc. At this stage, paper submission and edition have been completed. The congress program has been formulated and will be available online soon. For more updated information on the congress, please visit the congress website at www.isrm2011.com. Especially, the early-bird registration has been extended to July 31, 2011. Please grab the opportunity to enjoy the early-bird rate. We look forward to seeing you in this golden Autumn.

BEIJING IS READY TO WELCOME YOU!

Sincerely yours

chairmen

SANIRE offsets its 2010 carbon footprint by planting trees

In 2010, SANIRE Council supported the implementation of ‘green rules’ to reduce the impact of the institute’s activities on the natural environment with a green levy of R30 per member per year to be deducted from the member fees. This project was the brain child of Mr Friedemann Essrich. In 2010/11, a total of R10 920 was collected in this way. In order to put these funds to the best possible use, SANIRE approached FTFA (Food and Trees for Africa at www.trees.co.za), to identify possible projects within communities affected by mining. The funds were sufficient to purchase and plant 122 indigenous trees and three rural schools around Rustenburg were identified as beneficiaries:

  • 30 trees for Mperebere Primary School (Lerume Township)
  • 40 trees for Bakgofa Intermediary School (Ledage)
  • 52 trees for Borite Primary School (Mokgwase/Mabeleapudi)

FTFA arranged for trees of a minimum 1m height, compost for planting, a digging crew to dig holes before the auspicious day (phew!), and instruction cards branded with the sponsor's details for each tree. The trees chosen for the day included Rhus lancea (Karee), Oleaeuropaea subsp. africana (Wild Olive / Olienhout) and Combretum erythrophyllum (River Bushwillow / Vaderlandswilg).

On Friday, 11 March 2011, Les Gardner, Wouter van Aarde and Friedemann Essrich – kitted out with hard hats and spades - met up with Sipho Mathe and Emmanuel Sinthumule from FTFA at the Sun City Gates.

The first stop was Mperebere Primary School where learners were patiently awaiting the 'dignitaries' arrival. A ceremonial table had centre stage underneath a Scented Thorn (Accacia nilotica subsp. kraussiana) and chairs for the learners were crowded into its shade, but many had to endure the sun. Proceedings were opened with scripture and prayer, followed by a poem, a dance group, several drama groups and many thanks and festivities before moving along to 'the purpose of the day'.

The Bakgofa contingent had patiently waited for SANIRE to arrive, understanding the complexities of 'african time' and issued a very warm welcome to the visitors. The learners sat around the square and the dignitaries were again seated at ceremonial tables laden with snacks – luckily in the cool shade of the patio. The event was opened with prayer and then an extended introduction of all the persons involved with the day's program. The students entertained the guests with poems, song and drama – all themed on tree planting, as were the decorations. With time running out, the tree planting demonstration was held in the school yard before groups again split off to plant their trees. Within an hour another 40 trees were planted with the enthusiastic aid of the learners. Luckily FTFA had already planted the trees at the 3rd school.

Small in-pit radar increases safety in open cut mines

Always on the minds of persons working within open cut pits is the possibility for sections of a wall to detach suddenly and, with minimal warning, bring down tonnes of rock.

Since 2003 one of the most significant contributions to in-pit safety has been the development, application and refinement of in-pit radar for monitoring wall movement. Radar systems are now in use throughout the world. These systems have been designed to continuously monitor entire walls, or even entire pits, for 24 hours a day, 7 days a week.

There has however not been an easy to use rugged mobile system available that is specifically designed to target just the work zone around where a crew is working.

To address this issue, GroundProbe (wam.groundprobe.com) has released the Work Area Monitor (WAM). The WAM is a small high resolution radar that is mounted on a light mine vehicle which enables it to be deployed quickly to a work zone. Once there, it can be set up and running in less than a minute; a camera and radar enabling the work crew to quickly select the area to be monitored. The system continuously monitors that area for movements of large rocks or loose material as opposed to bench sized movements monitored by larger in-pit radar systems.

When the WAM detects movement it alerts the work crews via wireless Personal Alerts that display emergency text messages, audio, visual and vibrating alerts while at the same time sounding local lights and sirens to warn miners.

Slope Stability 2011 - Vancouver, Canada, 18-21 September

The Organizing Committee for Slope Stability 2011, together with the Canadian Rock Mechanics Association (CARMA), would like to invite you to Vancouver to discuss the challenges being faced in the design and management of large open pits in mining and the innovative solutions being developed in response to these challenges. This symposium will offer the complete professional development experience, together with short courses, social events, and other activities that will ensure a busy and enjoyable meeting in the city often rated as one of the World’s most desirable cities to live.

Slope Stability 2011 marks the return of this symposium series to Vancouver, where in 1970, the first "International Conference on Stability in Open Pit Mining" was held. This meeting was followed by a second meeting in Vancouver the following year. The purpose of these conferences was to review the state-of-the-art in pit slope engineering in practical terms. The conferences that followed included a third meeting in Vancouver in 1981 and a fourth meeting in Denver in 2000, which adopted the shortened name Slope Stability 2000. Subsequent meetings include those in Johannesburg (2006), Perth (2007), and Santiago (2009).

The Technical Program will examine the transformation our profession is undergoing as unprecedented amounts of quantitative data become available through new measurement and analysis techniques. The question is, how do we make sense of all the numbers and data that are now available? Topics to be considered include:

  • Assessment and implications of uncertainty
  • Ground water and in-situ stress
  • Monitoring and managing slope movements
  • Numerical analysis and design methods
  • Open pit-underground mining interactions
  • Pit closure and decommissioning
  • Remote sensing applications
  • Rock mass characterization for large rock slopes
  • Rockfalls - analysis and control
  • Slope design and acceptance criteria
  • Slope design in arctic conditions and extreme climates
  • Slope excavation, blasting techniques and quality control
  • Slope failure mechanisms
  • Slope performance, optimization and risk
  • Support, drainage and stabilisation of slopes
