Abstract

The manufacturing application experience at SUBR mines of a steel-polymeric roof bolts is given. New parameters of roof bolts, for SUBR excavations, based on theoretical and practical researches are obtained. The results of experimental-industrial tests of lateral excavation supported by new designed steel-polymeric roof bolts are shown. The economical estimation of the steel-polymeric support is given.
