The Shaft Boring Cutterhead (SBC) is developed for mechanized full-face shaft sinking in hard rock to a depth of 2,000 meters. The excavation sequence is highly automated.
Increased worker safety
Although on the SBC work steps are carried out in parallel, the machine concept significantly increases worker safety compared to conventional shaft sinking. During the excavation, personnel are not exposed to the unlined shaft wall.
Designed for efficiency
The design of the SBC is based on reference projects and is aligned with leading operators on shaft sinking activities. Each SBC is tailored to the specific requirements of the project to ensure the maximum support for safe and fast shaft sinking in each construction phase.
Higher advance rates
The full face cutterhead is equipped with disc cutters. It has a speed of 2 to 3.5 revolutions per minute and thus achieves high advance rates in relation to the geology. After an advance of 1 meter has been sunk, the SBC is lowered. The installation of the shaft lining from a work deck of the SBC is proceeded parallel to the advance and can be adapted to the requirements of the project.
Proven technology as the basis for new developments
The components used in the SBC have proven themselves worldwide in Herrenknecht shaft sinking and tunnel boring machines.
With the further development of existing technologies and profound engineering know-how, Herrenknecht opens up new business areas. In the field of mining in particular, innovative machine concepts are needed to safely and efficiently develop deposits even at great depths.
