Guidelines for Slope Performance Monitoring

June 25th, 2020|

The latest Large Open Pit Guidelines on Slope Performance Monitoring, the fifth in the series written by industry experts and international researchers, is now available online (currently pre-order only) through the links below: After the official launch in July 2020, interested readers will also be able to access it from book retail websites or by placing an order with their local bookshop. It will also be available in an eBook format around mid-July 2020. The 10 chapters present the process of establishing and operating a slope monitoring system, the fundamentals of pit slope monitoring methods and instrumentation, monitoring system operation, data acquisition, management and analysis, and utilisation and [Read more]

LOP III Meeting #1

May 18th, 2020|

In view of the COVID-19 situation, a scaled-down LOP III Meeting #1 was held online, focusing on Research Proposals for LOP III – Open Pit of the Future.  The meeting was held over a two-day period on May 11 from 7 – 10 am and May 12 from 12 – 3 am (Brisbane time) to accommodate time zone differences between the LOP Sponsors. LOP III – Open Pit of the Future will run for 3 years from 2020 to 2022, sponsored by at least 10 global mining companies, expected to include Anglo American, Anglo Gold Ashanti, Barrick, BHP, Debswana, Fortescue, Glencore, Newcrest, Rio Tinto and Vale. Other international mining companies also attended the meeting and are [Read more]

LOP Online Lecture by Prof. Evert Hoek

February 24th, 2020|

In this LOP Presentation, Professor Evert Hoek is providing insights into the use of rock masses as engineering materials with an emphasis on large open-pit mine slopes. The presentation is based on Prof Hoek’s recent public talk at a symposium in Brisbane in December 2018 for the celebration of the 80th birthday and the retirement of Professor Ted brown. The paper presented in 2018 was entitled “The Hoek-Brown Criterion and GSI 2018 Edition”, and is published in the journal of Rock Mechanics and Geotechnical Engineering. It is noted that the Brisbane presentation was for a general audience, and Prof Hoek has made several significant changes in this LOP presentation in [Read more]

LOP Online Lectures

October 12th, 2019|

The Large Open Pit Project invites international experts in the field of Slope Stability Design a few times a year and the video recordings will become available online for public access. The quality of the recordings does vary, and you may have to modify your volume levels when watching or look closely to see some slides. A list of available online lectures can be found here.

LOP Online Lecture by Dr John Read

September 20th, 2019|

The open pit mine Geotechnical Engineer is responsible for creating slope designs that are expected by the owners, management, the workforce, the regulators, and the public domain to be stable for the life of the mine. Economic requirements are always implicit in the designs, but in today’s world producing slope angles that ensure the workers in the pit are protected against death or injury have become additional moral and legal requirements. These factors require that the Geotechnical Engineer has a skill set that at a minimum: encompasses regional and site-specific knowledge of the geological model; understands the spatial and temporal distribution of the structural defects that are likely to affect [Read more]
