Large Diameter Crossover TBM: Success in Turkey & Future Applications

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.

Robbins Lecture

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.

Reach First Ore Quicker

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.

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.
