Bolt anchoring support, as one of the core engineering technologies for the stability control of surrounding rock in coal mine tunnels, is widely applied in underground engineering construction under ...

A debate over the use of fixed climbing anchors in designated wilderness areas has been simmering over the past couple months after federal agencies proposed new guidance that could impact their use.

Numerical simulation is an important method for analyzing the behavior of supports under complex geological conditions. FLAC3D, a widely used analysis tool, assumes the anchor structural unit to be an ...
