With the experience of more than 5,700 projects, Herrenknecht is a technology and market leader in the area of mechanized tunnelling technology. Herrenknecht is the only company worldwide to deliver cutting-edge tunnel boring machines for all ground conditions and in all diameters – ranging from 0.10 to 19 meters.
The product range includes tailor-made machines for traffic, supply and disposal tunnels, technologies for pipeline installation as well as drilling equipment for vertical and inclined shafts and deep drilling rigs.
As a reliable project partner, Herrenknecht supports its customers with an extensive range of services from the beginning of the project to breakthrough. With competent service specialists and more than 45 years of experience in the tunnelling industry, the company regularly supports around 300 jobsites worldwide and offers customized service packages tailored to individual project requirements.
Due to the constantly growing demand for ores it is becoming more and more attractive to extract raw materials underground at increasingly greater depths. Whether and when deposits are profitable also depends on the efficiency of the technology used to extract ore deposits.
We have therefore used our expertise in mechanized tunnelling to develop innovative machine concepts for a variety of applications in mining. Whether for vertical access or production shafts, inclined vehicle access ramps, ventilation shafts or transport routes, Herrenknecht technology is designed for smallest and largest diameters and can reach depths of up to 2,000 meters.
The innovative solutions are based on proven principles and stand for high advance rates and compact design. Herrenknecht's tunnelling technology is thus optimally designed for the safe, fast and efficient mechanized construction of shafts and galleries in all areas of mining.
Safe and fast full-bottom shaft sinking to depths of 2,000 meters
ALL ADVANTAGES AT A GLANCE:
- Innovative machine for mechanized full-face excavation of mine shafts
- Rock strength up to 250MPa
- Shaft depth up to 2,000 meters
- Shaft diameters from 7 to 12 meters
- High level of worker safety
- Increased shaft sinking speed
- Continuous muck removal from shaft bottom
Herrenknecht Gripper TBMs have proven to be efficient solutions for fast mechanized tunnelling in hard rock on many occasions. Due to the process-typical rock support method without segments, medium to high rock strengths are a requirement for high advance rates. In more fractured geological formations, various systems for immediate rock support behind the cutterhead are installed at the TBM directly.
The Herrenknecht Reef Boring Machine (RBM) safely and efficiently creates horizontal and ascending boreholes with inclinations of up to 40°. In stable rock with up to 300 megapascals and with excavation diameters of up to 1.5 meters, the RBM achieves borehole lengths of up to 40 meters.
