The ISRM Digital Library was launched – ISRM Members can download 100 papers per year for free

The ISRM Digital Library was launched in October 2010 during the New Delhi International Symposium.

The main aim of the ISRM Digital Library is to contain all the papers published in the ISRM Congresses and sponsored Symposia, thus giving them a greater visibility and making them available to all the rock mechanics professionals.

The ISRM Digital Library is part of OnePetro, a large online library managed by the Society of Petroleum Engineers. ISRM individual members registered on the ISRM website are allowed to download, at no cost, up to 100 papers per year from the ISRM conferences, and ISRM corporate members can download 250 papers.

To register on the OnePetro website (http://www.onepetro.org) as an ISRM member, the only necessary information is the username and the password used to access the members’ area of the ISRM website. Non-members can purchase the ISRM papers online.

The ISRM digital library has now 2,500 papers published in 11 conferences, and these numbers are expected to double in the next six months.

New initiative to identify core issues contributing to seismic risk in South Africa’s platinum mining sector

Earlier this year, the South African Mine Health and Safety Council awarded a 1-year research project to a consortium of mine seismology and rock engineering experts to establish contributing factors driving seismicity and rockbursting in platinum mines.

In its proposal, the project team suggested building on the gold mines’ experience when it comes to managing seismic risk. Gold mines have been operating digital seismic networks for over twenty years during which valuable insight was gained into the relationship between geotechnical setting, stress fields, mining practice and seismicity.

Notwithstanding past experience, there are clear differences between gold and platinum mines: Rock types, virgin and mining induced field stresses, the almost complete absence of regional fault systems on the platinum side to name only a few.

The project aims at exploiting similarities when it comes to underlying principles of mining induced seismicity and focusing on the differences between Witwatersrand gold mines and platinum mines in the Western Bushveld Complex. The two main task groups in the project relate to detailed rockburst investigations on one hand (see photo), and suitable practices and procedures that deliver information relevant to successful seismic risk management on the other. The latter refers mainly to seismic monitoring, geological mapping, rock mass property data and stress measurements.

The project commenced in August 2010 and will be completed by July 2011. Project management responsibility rests with SiM Mining Consultants; geotechnical and rock engineering aspects are covered by Middindi Consulting, seismic data analysis and theoretical mine seismology aspects by HAMERKOP Scientific Services.
