FEASIBILITY OF FLAME-JET TUNNELING. VOLUME I. SUMMARY REPORT
Analytical system studies were made to determine the configuration of a flame-jet tunneling system and its expected performance. These studies examined the flame-jet tunneler design, haulage system, power system, and shoring and lining problem areas. Similar studies considered in detail various aspects of the environmental control problem, including a determination of the environmental heat, fumes, and noise created by the flame jets, the design of air and water supplies to modify this environment, and possibilities for crew protection against a hostile environment. Three possible alternative modes for life support were designed and evaluated, and one was chosen as the recommended system. Studies were also made to determine the overall cost of flame-jet tunneling, based on the detailed cost estimates made in the component subsystem studies. Total costs of flame-jet tunneling are developed and compared with conventional methods. In an experimental program, a series of tests was made on two 'control rocks' to determine the effect of various burner parameters on spalling rate. For comparative purposes, information was developed on conventional tunneling methods. (Author)
