Robbins 2014 Webinar Series

Webinar 1: Lessons Learned from the Field: The Greatest Challenges in TBM Tunneling.

When tunneling through the earth, there are no guarantees. Difficult and unexpected ground can come up at any time, and knowing how to manage that risk can make all the difference. The condition could be a mixed tunnel face resulting in slowdowns, or dangerous rock bursting that threatens the safety of your crew. No matter the obstacle, advice from peers who have experienced and overcome such situations is often the best way to find a lasting solution.

Robbins invites you to join a panel of worldwide experts to find out the best practices for dealing with difficult ground conditions, as well as machine features that can turn a challenging project into a success story.

In this complimentary 60-minute webinar, you’ll get expert advice from Robbins employees who have seen it all. You’ll hear case studies from some of the world’s toughest hard rock and mixed ground projects in India, Turkey, Ethiopia, and more. Submit your questions to marketing@robbinstbm.com beforehand and get a well-researched answer during the 15-minute Q&A session.

Navigate Tunnelling with VMT

Navigate Tunnelling … VMT navigation systems have been developed for different types of advance machines and ensure that tunnels of even several kilometres in length will be driven to their destination with millimetre accuracy. They calculate all information automatically and in real-time that is necessary for navigating along the designed tunnel axis. They feature a modular software structure and easy-to use menu-guided operation, together with the latest measurement and communication technology  click here
