Static and Dynamic Analysis of Rock Bolt Support. Design Considerations for Deep Underground Protective Facilities

Abstract

Analytical investigations of two problems of hardening a deep underground protective facility--(1) the mechanical failure of a cavity under dynamic ground shock loading and (2) the material failure of a cavity penetration under overburden loading and repeated ground shock loading--are reported. Design requirements are derived for liner, backpacked liner, and rock bolt reinforcement, which function to prevent mechanical failure of cylindrical cavities sited in well-fractured rock and a step-by-step procedure for design is given.
