Rock bolting is the most commonly used method to support mine galleries and is also widely used in mining stopes. This guide is the result of a series of meetings, field studies, and review of the literature covering presently used bolting practices and the state of knowledge on this subject. The guide describes the mechanisms generally used to explain the effects of rock bolting, details the 4 principal types of support bolts in present use and the selection of rock bolting characteristics (bolt length and spacing) as a function of ground conditions. Appendices give a detailed discussion of test results, calculation methods, and other specific points.
