  • What’s New, What’s Next: TBM Equipment for the Mining

    Jun 05, 2017· Open pit mines are becoming depleted, and mining activities are reaching deeper. Longer access tunnels are needed. The mine planners and the TBM equipment designers must work together at an early stage in the mine planning to determine the optimum compromise between most desirable mine plan, and most beneficial application of TBM equipment.
