Abstract
The purpose of this program was to find the relationships that define the load-supporting characteristics of mechanical and resin bolt types to determine roof bolting specifications that will lead to objective comparisons between resin and conventional bolt types and yield useful data related to hole spacing and roof support characteristics. Creep properties for bolted joints were used in finite element analyses of sections of the White Pine Copper Company Mine that included analyses of bed separations in the roof and sloping faults. In situ experimental measurements were made of tension, compression, and bending of resin bolts by use of strain- gaged bolts. Evaluations of bolting effectiveness and comparisons of predicted and measured roof behavior are given. Volume IV contains Appendix D, a listing of computer program sap-s.
