Product Description
It is very common for underground works to encounter soft surrounding rock, fractured zone and
great deformation due to high ground stress. It is difficult for anchor work, especially under the condition
that serious hole collapsing occurs and extra-long bolt is needed, while it is impossible to solve the problem
with ordinary bolt. This self-drilling bolt embodies drilling, grouting and anchoring as a whole and can
improve the condition of surrounding rock in the course of deformation due to high ground stress.
