TERRATEC Delivers the First Large Raise Borer for China

TERRATEC Delivers the First Large Raise Borer for China
TERRATEC has successfully completed the factory testing and delivery of a new TR3000 Raise Boring Machine on June 19, 2015. The event was held in the company’s workshop in Tasmania, Australia.

The destination of the machine is a new one: China. Mining companies and raise boring contractors in China have been using raise boring machines for years, but almost all of those have been locally produced with a nominal diameter always smaller than 1.8 m.

The mines where the raise borer will work are located in Yunnan Province, where the main mineral extraction is copper. As the mines develop deeper levels, the access requirements for services such ventilation, mineral pass, etc., increases, so the mines are now looking into bigger shafts that require larger machines.

TERRATEC’s TR3000 model has a nominal boring size of 3 m capable of reaching 500 m in depth. The machine uses a standard pilot hole of 311 mm in diameter and it has a maximum pilot drilling torque of 78,000 Nm, reaming torque to 237,000 Nm and breakout to 266,000 Nm. The down thrust maximum force is 1,600 kN with up thrust being 4,500 kN. The total installed power on the machine is 352 kW. The

After extensive research and analysis, the mining contractor selected TERRATEC based on its highest quality standards, the company’s well tested technology over the last 25 years, and the short delivery time.

TERRATEC has similar raise borers working around the world, especially in Australia and North and South America mines. With this one, TERRATEC achieves an important milestone expanding its sales into the Chinese market, where there will be many opportunities for the supply of large raise borers like this one in the coming years.
