Design Criteria for Roof Bolting Plans Using Fully Resin-Grouted Nontensioned Bolts to Reinforce Bedded Mine Roof. Volume IV. Theoretical Analysis

摘要

Investigations were conducted on axial and shear loading of resin bolts, the Voussoir rock arch, beam building, angle bolted roof trusses, jointed roofs, bolting of sloping joints, and stresses in roofs due to moisture changes. The analyses described here are supplemental to those described in Volume I.
