Description

technical field [0001] The invention relates to a roadway support tool, in particular to a combined mine bolt. Background technique [0002] Roadway support is mainly to provide a certain support resistance to the surrounding rock, or to strengthen the surrounding rock to form a reinforcement layer in the shallow part of the surrounding rock. Its essential function is to control the separation, sliding, crack opening, and new Expansion deformation and destruction such as crack generation form a secondary bearing structure with higher rigidity in the anchorage area to control the development of the plastic zone of the surrounding rock, prevent the rock formation outside the anchorage area from delamination, and improve the stress distribution state in the deep part of the surrounding rock. The ultimate goal is to reduce the displacement of surrounding rock and keep the surrounding rock stable. Anchor is a common method of surrounding rock reinforcement and support in ground ...
