MATERIALS HANDLING RESEARCH FOR TUNNELLING

Recent research at the Colorado School of Mines has focused on the materials handling problem of muck haulage in rapid transit tunnels. For the muck rates projected within the next decade, high-volume transportation modes will be required. Hydraulic and pneumatic pipelines appear attractive as high capacity haulage systems serving a confined space. Slurry pipelines are examined here in detail with special reference to muck preparation, extensible conveyor systems, slurry pipelining, and slurry dewatering. Pipeline efficiency and reliability depend on a controlled particle size and distribution. Therefore, some crushing of the muck will be necessary. A simple means for temporarily extending the transport system between muck preparation and slurry pipeline is necessary for high capacity-continuous operation. Assuming that the slurry water is recycled to the tunnel face, dewatering schemes must be considered. Technical feasibility is demonstrated in these areas.
