    A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They may also be used for microtunneling. They can be designed to bore through anything from hard rock to sand. Tunnel diameters can range from one metre (3.3 ft) (done with micro-TBMs) to 17.6 metres (58 ft) to date. Tunnels of less than a metre or so in diameter are typically done using trenchless construction methods or horizontal directional drillingra

    IntroductionBackgroundConventional Hard Rock MiningTBM OperationTBM Drive Heat LoadsThermal Energy Balance and Cooling RequirementsVentilation System and IntegrationOccupational Hygiene and Health and SafetyConclusionsReferencesTunnel Boring Machines [TBMs] are used for large bore, rapid tunnel excavation. TBMs typically have a circular cross section between 1 m and 8 m and can bore through a variety of soil and rock strata. The cutter head typically rotates at between 1 and 15 rpm, depending on the TBM diameter and the rock type. The advance rate of TBMs can vary between 10 m/day and 60 m/day, depending on the ground conditions. Mine planners hSee more on mvssa.co.za
