Proceedings of Workshop on Materials Handling for Tunnel Construction Held at Keystone,Colorado on August 3-5, 1977,

摘要

With the anticipated increases in tunnel construction in the next decade greater demands will be made on transportation systems to remove tunnel muck at rates consistent with tunnel excavation rates. Conventional materials-handling systems such as rail,rubber-tire vehicles,and conveyors will have to expand their capabilities. Simultaneously,hybrid and lesser known systems such as pneumatic and slurry pipelines must be considered as potential systems for muck haulage,particularly since they show substantial promise of being capable of transporting the muck volumes projected for the next decade. A workshop entitled, 'Materials Handling for Tunnel Construction',was held August 3, 4, 5, 1977at Keystone,Colorado. Experts were invited from the construction,metal and non-metal mining industries. The participants evaluated the state of the art of materials-handling systems for underground construction,exchanged information on current systems applications and research,itemized research needs,and produced a written summary of their conclusions. This report comprises the proceedings of the workshop.
