TERRATEC successfully completed the factory acceptance testing of its first raise boring machine sold for the Mexican market. The ceremony was held in Tasmania, Australia, in the presence of the client, Ing. Gabriel Elizondo, of Cau S.A. de C.V. (CAUSA) of Mexico after six months from receipt of order.

CAUSA was founded in 1978 as a service company for development of mining and civil works. The company has been exploring all types of mineralisation in the majority of Mexico and it is the largest raise boring contractor in the country.

The TR3000 raise boring machine is robustly designed for easy use and high reliability. This machine is capable of boring a 3m diameter hole up to 600m deep in hard rock. The design and production was fully done by TERRATEC in Australia.

The nominal hole diameter for this size of machine is 3m with a standard pilot hole diameter of 311mm. The machine has a pilot drilling torque of up to 78,000Nm, reaming to 237,000Nm, makeup to 261,000Nm and breakout to 266,000Nm. The down thrust is calculated at 1,600kN with up thrust being 4,500kN. The total installed power on the machine is 352kW.

The dimensions of the machine were a critical element with the derrick extended height of 4,500mm and retracted at 3,815mm. This machine will fit within the drift requirements as specified during negotiations.
