A boring machine is a special drill designed to bore large holes or tunnels into the earth. These machines can drill both horizontally and vertically. This makes them a good tool for building tunnels into mountains or other hard rock material. Mining companies dig tunnels deep into the core of the earth looking for raw materials.
Known as the MDM5000 (standing for Mine Development Machine), the TBM has dimensions of 5 m x 4.5 m and is capable of excavating a flat tunnel invert for immediate use by rubber-tyred vehicles, Robbins says. The successful operation is the result of extensive discussions between tunnel boring machine (TBM) and mining equipment manufacturer ...
Increase Tunneling speed. Tripling TBM Power increase power while improving cooling systems (more power more speed) Continuous Mining installing the tunnels precast segments simultaneously with mining eliminates the need to stop the TBM every five feet (these stoppages are standard on soft-soil TBMs) Surface Launch and Porpoising Prufrock arrives on a truck,

A Tunnel Boring Machine Makes Mining History in Australia. Mining was recently revolutionized in Australia by use of mechanical tunnelling technology for the Grosvenor Decline Tunnel Project, owned by Anglo American. The project, a greenfield site for a coalmine, required decline tunnels for access to a deep coal seam within a tight time ...
Aker Wirth raise boring machines and cutters have been in operation in the hardest rock, up to 700MPa USC. The equipment ranges from 112kW to 600kW installed power, the cutting diameters from 1m to 6m and the boring depths up to 1,300m. Aker Wirth built the worlds largest raise borer, the HG 380 with an operating torque of max. 710kNm.
Raise boring is used to drill shafts for ventilation, transferring ore from one level to another, creating silos for storing rock as well as hoisting of rock and ore to the surface. The application of Raise boring in mining also assists in providing access for personnel or material underground.
