Complimentary Webinar: Know What's Ahead of You
Your project has to keep moving forward, whether the challenge is high cover, squeezing ground, fault zones, or water inflows. New ground investigation and treatment options can give you the tools to conquer what you face while maximizing TBM performance and safety.
In this complimentary 60-minute webinar, Robbins Chief Engineer Dennis Ofiara will discuss Difficult Ground Solutions (DGS)–a suite of options available for shielded hard rock and Crossover TBMs that can keep your machine moving in long tunnels, high cover, and challenging geological features. DGS is about visualization: A machine shield doesn’t have to obstruct your view of the ground around you. With a host of features like 360-degree, long distance probe drilling, convergence measuring sensors that alert operators to squeezing ground, and canopy drills for ground consolidation, you can stay a stroke ahead of your TBM operation.
We invite you to submit your questions beforehand to webinars@robbinstbm.com to get a thoughtful and well-researched answer from Dennis during the Q&A session at the end of the webinar.

Tunnel Boring Machines exist today that have excavated over 50 km (31 mi) of tunnel, and have been in operation for nearly 50 years. These workhorses have been built and rebuilt to satisfy requirements of various tunnels while their durable steel structure endures.
Today’s underground construction contractors often face a higher capital cost during the initial investment for a TBM, but what is the total cost of owning a TBM? Much more than the initial price tag must be taken into account: while a heavier TBM with durable steel structure may cost more initially, reusing it on multiple tunnels will ultimately result in substantial savings. Paying for a custom-designed machine often results in increased efficiency and faster advance rates, with the end result that the tunnel is completed on or even ahead of schedule.
In this complimentary 60-minute webinar, Robbins Vice President-Sales Doug Harding will explore the true cost of owning a TBM, considering the entire lifespan of the machine. He will draw on real project data and cost estimates to demonstrate that a machine designed for multiple tunnels will pay for itself over time.

Today’s mine development projects are no longer being done from the surface. Worldwide, easily accessible ore deposits have been spent, requiring mines to aim for deeper ore bodies, often kilometers underground, to keep operations viable.
This changing mine environment brings a need for access tunnels, first to reach the ore, then to provide long-term muck haulage. Tunnel boring machines provide efficient, safe, and fast access to those ore bodies. Mines around the world are accustomed to methods such as drill & blast, roadheader, and other types of conventional excavation. However, TBMs have been proven on multiple projects to complete tunnels two to three times faster than drill and blast; when considering roadheaders that number is often 10 times faster.
In this complimentary 60-minute webinar, Ryan Gratias, Project Engineer at Robbins and Adam Foulstone, General Manager-Grosvenor for mining company Anglo American, will discuss the changing face of the worldwide mining industry. From machine design to application and real-world examples, Gratias will prove that early adopters of the TBM method will be able to better meet increased demand and extend the life of their mine. Foulstone will discuss the recent use of a Crossover (XRE) TBM at the Grosvenor Decline Tunnel in Australia™ wildly successful use of a TBM that resulted in access tunnels bored 14 times faster than the traditionally-used roadheader method.

Complimentary Webinar: A Myth Dispelled by President Lok Home

In the modern-day tunneling industry, one outdated perception remains: Traditional, tested methods are always the best. When presented with difficult ground””from fault zones to water inflows to mixed face conditions””many consultants and contractors rely on decades-old field studies and conclude that conventional excavation methods like drill and blast are the best option. With today’s Tunnel Boring Machine (TBM) technology, this assumption couldn’t be further from the truth. Modern TBMs are highly adaptable and capable of offering all of the same ground support and excavation capabilities of their conventional counterparts””most often with a safer setup and faster performance, not to mention at a lower overall cost.
In this complimentary 60-minute webinar, Robbins President Lok Home will analyze recent tunneling projects in difficult ground conditions where TBMs have proven their worth, including Turkey’s Kargi Kizilirmak Hydroelectric Project and Peru’s Olmos Trans-Andean Tunnel. At Kargi, a shielded hard rock TBM overcame incredibly difficult mixed face conditions with the help of in-tunnel machine modifications””ultimately completing the tunnel at an advance rate more than twice that of a drill and blast operation proceeding from the opposite end of the tunnel. At Olmos, the world’s second deepest civil works tunnel, a TBM ultimately succeeded at boring where drill and blast had failed: below 2,000 m of volatile volcanic rock in the Andes Mountains.
