Non-Circular Tunneling in Rock: A New Way Forward
Presented by Lok Home, Robbins President
Event Name: CIM Convention
Location: Vancouver, BC, Canada
Dates: May 1-4, 2022
The CIM Convention focuses on the future of mining. Join Robbins at the conference for a presentation with Robbins Technical Director, Brad Grothen, P.E., on new innovations for underground mining in rock. Keep an eye out for Abstract Number 252: Faster Underground Mine Development: Getting to First Ore Quicker using a Novel, Non-Circular Tunneling Machine – date and location coming soon! Find out how to reach your ore body quicker, safer and more cost effectively in this talk.
Large diameter tunneling in mixed ground has historically been seen as a challenge, but a recently completed tunnel in Turkey has changed the conversation. A 13.77 m diameter Crossover XRE TBM bored the Esme Salihli Railway Tunnel at world-record-setting rates of up to 721.8 m in one month, making it the fastest TBM over 13 m in diameter.
Join tunneling experts Brad Grothen P.E., Robbins Technical Director; Şevket Kılıç, TBM Engineer for contractor Kolin Construction; and Prof. Dr. Nuh Bilgin, Chairman of the executive board of the Turkish Tunnelling Society in this complimentary, 45-minute webinar. We’ll discuss the remarkable advance rates, experiences, and future applications for Crossover machines both within Turkey and worldwide. A live Q&A session will be held at the end where you can get a thorough answer from our expert speakers.

Join experienced Robbins staff at the largest trenchless technology conference in the world, NASTT No-Dig in Minneapolis, MN. Find out more about our line of Robbins Small Boring Units (SBUs) —game changers in the trenchless industry, saving you time and money on your next hard rock or mixed ground utility tunnel.
Join us December 21st and 22nd for the Tunnel Turkey International Tunnelling Symposium in Istanbul. Our team of international experts will be speaking on Robbins’ latest products and projects during the conference, including non-circular innovations for hard rock tunneling. Stop by Robbins’ stand 8 to find out more on our projects in Turkey, including our record-breaking project in Esme! The Esme-Salihli project has bored 32.4 m in a day, 178.2 m in a week, and 721.8 m in a month using Robbins Crossover XRE machine, making it the fastest machine over 13 m in diameter ever recorded.
Non-Circular Tunneling in Rock: A New Way Forward
Presented by Brad Grothen P.E., Robbins Technical Director
Abstract: When a flat roadbed is needed, is a circular TBM the best way to go? In this presentation, Robbins Technical Director Brad Grothen will discuss a mechanical boring machine currently being used in the mining industry for a rectangular tunnel cross section, and the potential for use of this machine in civil tunneling. Grothen will also look at emerging technology to demonstrate that by using non-circular TBMs, a flat invert can be safely and economically created in one pass.
Deep underground ore bodies require a new approach: Rectangular rock boring machines create access and development drifts with flat inverts that enable immediate use of the tunnel by rubber-tired vehicles. These non-circular tunnel boring machines bore tunnels in rock up to 200 MPa UCS at twice the rate of drill & blast, and with fewer ground support requirements. Find out how to reach your ore body quicker, safer and more cost effectively in this exclusive webinar in conjunction with Mining Magazine.
In this recorded, 60-minute webinar you’ll learn about the successful use of a rectangular rock boring machine at Fresnillo silver mine in Mexico, where the equipment has advanced more than 1,700 meters at rates of up to 191 meters in one month. Listen in as Robbins President Lok Home discusses ongoing developments for underground mining, including ways to directly mine the ore body using tunnel boring machines. The presentation will conclude with a discussion on future developments in underground mining, moderated by Mining Magazine.
Join Robbins at the most important Mining exhibition in Latin America! EXPOMIN will be hosted in Santiago, Chile from October 25th to the 29th. Come learn more about the astonishing work our MDM5000 has been doing at the Fresnillo Mine–the first successful use of a rectangular rock boring machine. Our team of professionals are eager to meet and talk about a solution for your next underground mining project. Check out this map of the exposition hall and look for the Robbins R to find our stand location 3-F21. Stop by to see our latest products and projects!
Come join us in Acapulco, Guerrero at the 2021 Mineria International Convention and learn more about Robbins’ latest innovation, the MDM5000. 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.
