Rock burst active prevention and control mechanism

A rock burst active prevention and control mechanism, wherein, comprising:

• a negative Poisson's ratio (NPR) reinforcing mesh, rod bodies, NPR steel panels, an embedding reinforcement and a NPR steel fibre concrete;
• the NPR reinforcing mesh is formed by horizontal and vertical interlacing of NPR steel bars, and the NPR reinforcing mesh is provided against a surrounding rock of a tunnel;
• the rod bodies are NPR bolts or NPR anchor cables, the rod bodies are anchored in the surrounding rock of the tunnel, and extending ends of the rod bodies are penetrated out of a hole of the NPR reinforcing mesh;
• the NPR steel panels are provided with multiple through-holes, which are configured for passing through the extending ends of the rod bodies, and the NPR steel panels are pressed onto the NPR reinforcing mesh via an anchorage;
• the rod bodies, which are located on a same radial plane in the tunnel, are connected to one of corresponding NPR steel panels;
• the embedding reinforcement is connected between the extending ends of two adjacent rod bodies;
• the NPR steel fibre concrete is overlaid on the extending ends of the rod bodies and the embedding reinforcement, the extending ends of the rod bodies are provided with at least two layers of embedding reinforcement, the embedding reinforcement comprises a radial embedding reinforcement extending along a radial direction of the tunnel, the radial embedding reinforcement is connected to the extending ends of the rod bodies which are located on the same radial plane in the tunnel, and the embedding reinforcement comprises an axial embedding reinforcement extending along an axis direction of the tunnel, the axial embedding reinforcement is connected to the extending ends of the rod bodies located parallel to a tunnel axis, and the embedding reinforcement comprises a slant embedding reinforcement, which is connected to the extending ends of the rod bodies located on a direction which is different from the radial direction of the tunnel and an axial direction of the tunnel;
• the embedding reinforcement is connected to the extending ends of the rod bodies via a fixture.
