MATERIALS HANDLING FOR TUNNELING

At the tunnel face advance rates anticipated for the future, material handling could become the critical factor in the tunneling project. All functional elements of the tunneling process require materials to be moved by the materials handling system. The characteristics, quantities, and flow of muck, ground support materials, materials for transport system extension, personnel, and other materials and equipment which must be transported between the surface and the work zones are defined. Candidate transport modes to meet the requirements of the future are classified as continuous flow systems or utilized transport systems. Conveyors, hydraulic pipelines, and pneumatic pipelines are selected as representative of continuous flow systems. Conventional dual rail systems with locomotive drive, side-wheel drive and cable drive, siderail systems, monorail systems hoist, and truck systems are selected for evaluation in the unitized category. These ten transport modes are described, discussed, and analyzed through computerized mathematical models representing the cost/performance relationship for each system. Integrated systems including all elements of the total materials transport system throughout its total life cycle are conceived and analyzed. Based on the results of these evaluations and analyses, areas are identified for beneficial allocation of research and development resources to advance the state of the art of materials handling for tunneling.
