Abstract:

This is the magnetic tape containing computer programs listed in Volume 2 of the final technical report generated under contract H0110238. A computer model of the overall hard rock tunneling process which considers both performance and costs of the operation was developed. Segments of the tunneling process modeled include geology, fragmentation methods, muck removal, ground support, and environmental considerations. A three-dimensional stratified geology model, functions as a data file to represent geological conditions in the area surrounding the tunnel. The user has a choice of simulating rock fragmentation by drill and blast, boring machine, high velocity water jet, and projectile impact. He may also simulate either rail, truck, or conveyor belt haulage systems. Steel sets, shotcrete, and rock bolts are offered as a choice of ground support methods. Environmental factors considered include water removal, ventilation, and cooling. A cost accounting system is incorporated to provide cost-benefit analysis of tunneling system performance. Author
