NTIS: PB/84-113216 :224 pages
The objective of this three-volume report was to develop a system to reduce the costs, safety hazards, and time currently required in lining mine shafts with concrete. The continuous shaft lining (csl) system will line machine-bored shafts downward from the shaft collar on a continuous basis using an inverted, pressurized slipforming technique. Volume I describes the basic csl concept, the design and operation of a prototype unit, and estimates of cost.
