Anchorage performance of a high-pressure pre-tightening resin anchor with a compressed grouting body
Supports for deep mine roadways located in soft surrounding rock face several problems: difficulty in applying pre-tightening force, low bearing capacity, and poor initial support. To solve these problems, this study proposes a high-pressure pre-tightening resin anchor with a compressed grouting bod...
