The South African National Committee on Tunnelling (SANCOT) has pleasure in inviting you to a Breakfast Talk
Development of Generation 2 of the Shaft Boring Roadheader
During the last few years, companies have been moving away from “conventional” mining methods to more mechanized mining. This has come about due to the cost of labour but also due to safety reasons. One of the more diffi cult activities to mechanize is the shaft sinking process. This is not only due to the technical diffi culties but also because of the cost of the equipment, especially if used to sink just one shaft. Herrenknecht has been involved with mechanized tunneling for over 40 years now and two Shaft Boring Roadheaders (SBR) have now successfully completed two shafts to a depth of around 1000m at BHP Billiton’s Jansen project in Canada.
This presentation covers how shaft-sinking machines at Herrenknecht developed and the various types of shaft sinking machines available for the various ground conditions. The Jansen project is then briefl y discussed with the learnings from the project. The next generation of the SBR is then discussed, referring specifi cally to the two new projects, Nezhinsky project in Belarus and the North Yorkshire Polyhalite Project.
