Abstract
This federal Bureau of Mines report presents the design analysis, laboratory testing, full-scale crib testing, and analysis of results of steel-fiber-reinforced concrete mine support members developed at the Spokane (Washington) Research center. The objective of the work was to design and laboratory-test fiber-reinforced concrete mine support members for best configuration, fiber material, fabrication method, handling, strength, stiffness, and cost. The results indicate the steel-fiber-reinforced concrete (sfc) support members that were developed offer significant improvements in stiffness and strength in compression compared with wood supports, yet they avoid the brittle or catastrophic compressive failure mode of plain concrete. The results also indicate sfc support members may offer significant cost savings compared with wood supports.
