ABSTRACT:
Means and method for improving productivity and quality of grouted rock bolt installations. The invention provides means of automatically installing full length grouted bolts as well as tensioned (point anchor) grouted bolts, which ensures proper shredding of the grout package, proper mixing and proper curing of the grout, and minimizing machine time involvement. The invention also makes it possible to include a test for quality on each grouted bolt installed, within the automatic installation cycle. The invented means further allows control of the depth of holes drilled for rock bolting and automatic freeing of drill steels, where they may be danger of drill steel binding during drilling for rock bolting.
