conveyor provider for tunnel excavation

A Tunnel Boring Machine Makes Mining History in Australia ...

Tunnel length was dependent on the location of the coal seam. Called blind headings, the TBM ceased excavation in each tunnel once the coal seam was reached. Once the coal seam took up approximately 50 percent of the tunnel diameter, tunnelling for that access decline was considered complete. For both tunnels, this was around the 1,000 m mark.
