Machines Used In Gold Mining Ppt

2010-1-12TBMs have been used in mining operations from time to time almost as long as TBMs have been operation. Unfortunately, they have not been nearly as successful as in civil tunneling. The earliest application of TBMs in mining dates back to late 50s. This was followed by several attempts in 60s and 70s in other underground mining operations.
