Terratec has successfully completed the factory testing and delivery of a new TR3000 Raise Boring Machine. The destination of the machine is in the Chinese Province of Yunnan, where the main mineral extraction is copper. Despite the mining companies and raise boring contractors in China having used raise boring machines for years, almost all have been locally produced with a nominal diameter smaller than 1.8 m.

As the mines develop deeper levels, the access requirements for services such as ventilation and mineral passes increases, requiring bigger shafts. Bigger shafts require larger machines such as the TR3000.

Terratec’s TR3000 model has a nominal boring size of 3.0 m-diameter and 500 m depth capability. The machine uses a standard pilot hole of 311 mm-diameter. The total installed power on the machine is 352 kW. Click here for further information. Visit http://www.terratec.co/. 29/15.
