  • Mechanized Mining: Are TBMs the Way into the Future?tunnel

    The common perception in mining is that TBMs are large and unwieldy machines, but we have used them successfully for 24 years. The platinum and palladium mine first purchased a 4.0 m diameter Kellytype TBM in 1988 to excavate a mine access tunnel through the areas characteristically layered gabbro, norite, and anorthosite rock.
