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.
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.
A discussion of ongoing developments for underground mining, including ways to directly mine the ore body using tunnel boring machines, will follow.
