Abstract

The effect of the roadway supporting not only depends on the supporting force itself, but also depends on the surrounding rock, quantity of supporting placement, time and quality of setting up, and contacting points and surface in the surrounding rock. The classification, nature and failure mechanism of the surrounding rock are analyzed ,the author propose a new hanging and assembled supporting structure of the underground tunnel, and also analyzes its working mechanism and the reliability. This structure takes use of the interaction and common loading mechanism of the surrounding rock, it also offers a certain shrinkage value to achieve effective supporting effect. With pre-strength mortar bolt, resin bolt or advancing bolt together, we can more effectively prevent the surrounding rock loose to ensure the timeliness and effectiveness of the rock support.
