In the last three months the TR2000 completed five shafts with lengths varying from 100 to 200m and with reaming diameter of 1.8 and 2.1m. Each raise was completed in a time between eight and 13 working days, including both the pilot hole and the reaming. Terratec announced.
The TR2000 achieved peaks of advance between 15 and 17m in one single shift of 10 hours on each of the five shafts, which has set a production record in the history of the mine.
