The Tunnel Boring technology is specifically designed for horizontal and inclined hard rock applications; eliminating the need to drill and blast.
The high-level automation allows us to excavate tunnels with a smooth circular cross-section, safely and cost effectively.
Access tunnels to ore bodies in decline-type ramp or horizontal haulage format.
Used for metro utility waste water pipes,
communication etc, & railway infrastructure.
Hydro-electric or pump storage projects for the use of tailrace tunnels.
Allows for simultaneous cutting, loading, meshing and bolting.
Allows for mobility and steering in all directions during excavation.
Capable of transportation in vertical shafts (fits into standard cage dimensions and low areas with 2m height restriction)
Our Mobile Tunnel Borer “MTB” is a versatile mechanized solution to excavate a variety of tunnels in hard rock applications, eliminating the need to drill and blast.
The MTB has specifically been designed for the unique challenges in the mining sector. The compact and modular design distinguish it from conventional tunnel boring machines and allows it to operate on a 12º incline/decline, while maintaining a 30m turning radius and can be dismantled and returned to surface after the project has been completed.
The highly automated solution allows tunnels to be excavated with a smooth circular cross-section, safely and cost effectively.
Contact us and we will tell you more about our tunnel boring offer.
The MTB system is specifically designed for the mining sector, but also has multiple applications across civil and energy-related projects. The machine can be utilised to excavate a variety of tunnels including tunnels to underground ore bodies such as declines, portals, haulages, inclines, ramps, ring roads and connecting tunnels etc.
To initiate cutting, the MTB requires a rounded profile side wall to grip and thrust the machine forward. For this reason, a starting frame is assembled in advance of the next heading to be tunnelled. Once the backup of the MTB has advanced through the starting frame, it can easily be disassembled and moved to the next location where a new heading will begin – this process will then be repeated. For breakaways, the MTB relies on a starting chamber that will be excavated and made safe by cyclical conventional mechanised drilling, blasting, scaling, loading, supporting and hauling equipment.
