Tunnel boring machine Wikipedia
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 strataThey may also be used for microtunnelingThey can be designed to bore through anything from hard rock to sandTunnel diameters can range from one metre (33 ft) (done with microTBMs) to 176 metres (58 ft) to dateOr rather, interesting boring machines One in particular comes to mind, from the historic coal mining community of Roslyn, Washington: From Roslyn local historian, Sue Litchfield: Steeppitched mines predominated the RoslynCle Elum Coal Field, making it more expensive to extract coal than the relatively flat coal seams in the east and MidwestEven boring machines can be interesting – From Our Corner
TBMs in Mining | The Robbins Company
Robbins’ close partnership with the mining industry spans decades, from noncircular prototype machines such as the Mobile Miner to early TBM usage in coal, copper, and gold mines worldwide While those early machines were successful, modern machines are vastly more powerful and efficient than those tested and used in the 1970s and 1980sThe tunnel boring machines (TBM) are continuous mining equipment designed for the excavation of circular tunnels until more than 15 m of diameter at the moment(PDF) Application of tunnel boring machines in underground
