The machine has bored more than 1,700 meters of a mine access tunnel in andesite and shale with quartz intrusions. Stop by the TOPO/Robbins booth 706-706A to see the astonishing work that has been done at Fresnillo mine in Mexico. Meet with Robbins international experts who are ready to discuss a solution for your next underground mining project.
Event Name: Cutting Edge Conference
Dates: November 15-17, 2021
Location: Dallas, Texas, USA
Come visit Robbins at the Cutting Edge Conference, and learn more about the largest hard rock TBM ever to operate in the USA at the Mill Creek Project. The 11.6 m (38.1 ft) diameter Robbins Main Beam TBM is excavating an 8 km (5 mi) long tunnel in Dallas, and is the conference’s main field trip. The annual Cutting Edge Conference examines the latest advances in tunneling technology, its methodology and how they can be harnessed to assist the nation’s major upcoming underground projects. Visit Robbins at our booth and talk to our experts with decades of experience on our latest projects and products.
Covering more than 30 acres, The Utility Expo is the largest event for utility professionals and construction contractors seeking the latest industry technologies, innovations, and trends. Visit Robbins at our indoor booth N1961 and talk with our expert staff on our latest products and projects. We look forward to seeing you there!
Register for the British Tunnelling Society’s upcoming conference and learn about the industry’s latest trends with 800+ other tunneling professionals. Debate and analyze the latest trends and topics in underground construction, and be sure to check out the lecture by Robbins President Lok Home. Stop by our stand B26 to talk about the latest Robbins products and projects with our team of international experts.

Session 3 – Innovation in Action
2:00 – 2:20 PM
Non-Circular Tunnelling: A New Way Forward – Lok Home, Robbins President
When a flat roadbed is needed, is a circular TBM the best way to go? In this exclusive presentation, Robbins President Lok Home will discuss methods and equipment currently being used in the mining industry for flat inverts, and its increasing potential for use in civil tunneling. Home will look at case studies in both mining and civil tunneling industries to demonstrate that by using non-circular TBMs, a flat invert can be safely and economically created in one pass.
When you’re faced with a hard rock tunnel on your next small hydro project, which tunneling method works best? Intake tunnels can be at diameters as small as 2 meters and at steep grades of up to 45 degrees. Compared with the conventionally used method of Drill & Blast, small diameter tunneling machines offer increased production rates and reduction in cross section, among other benefits. The uniquely designed machines are engineered to take on steep gradients, and can bore tunnels kilometers long with minimal impacts to the surrounding environment.
In this complimentary, 60-minute webinar we discuss the use of small diameter tunneling machines on projects throughout Norway, where their popularity is increasing, as well as the method’s suitability on projects worldwide. Listen in on our conversation with Robbins Norway General Manager and Civil Engineer Sindre Log as we discuss recommendations for small hydro tunnels in hard rock. Join us for a live Q&A session at the end to get a thorough answer from our expert speaker.
When you’re faced with a hard rock tunnel where there are expected significant sections under high water pressure, which tunneling method do you choose?
While Slurry Shield tunneling has a long history of addressing this problem, this method has not always been problem free. Another highly effective method exists that can lower costs and risks: Non-continuous Pressurized (NCP) TBM Tunneling with a shielded machine. When used in rock with a comprehensive grouting program or sequential advance in EPB mode, NCP TBMs have proven that they can successfully navigate high water pressures safely and effectively.
In this complimentary, 45 minute webinar we debate the pros and cons of Slurry and NCP TBMs, and look at case studies of both types of machines in hard rock under high water pressures. Listen in on our conversation with Robbins President Lok Home and Brad Grothen P.E., Robbins Technical Director, as we discuss recommendations and the future of tunneling in rock under water pressure.

8:30 AM Session – Difficult Ground
Rock Tunnels at High Water Pressure: Non-Continuous Pressurized TBMs vs. Slurry
Presented by Brad Grothen, Robbins Technical Director & Lok Home, Robbins President
Event Name: BTS Evening Meeting with Lok Home
Location: Virtual Event
Attend the upcoming BTS Evening Meeting, a complimentary event for members and non-members alike. The talk and Q&A will be streamed live on YouTube.
When boring through the earth, even extensive Geotechnical Baseline Reports can miss fault lines, water inflows, squeezing ground, mixed face conditions, rock bursting and other geological challenges. That reality is compounded when tunnels are extremely long, in remote locations, or under high cover.
In this lecture, Robbins’ President Lok Home will discuss three of the most challenging projects in recent memory: The 43.5 km long AMR Water Tunnel, the geologically diverse Sleemanabad Carrier Canal (both in India), and China’s Yin Han Ji Wei project in challenging rock bursting conditions.
