Multi-section anchoring force increasing anchor rod and mine supporting structure

The utility model relates to the technical field of mine development, in particular to a multi-section anchoring force increasing anchor rod and a mine supporting structure, which comprises a sleeve and a rod body, and the rod body is inserted into the sleeve; a plurality of groups of blocking devices are arranged on the inner wall of the sleeve and are used for blocking the sliding of the rod body; the rod body is provided with a protruding compression device corresponding to the blocking device. Compared with the prior art, due to the fact that the sleeve is bonded by the anchoring agent, the anchor rod anchored in the deep portion of the rock mass, the sleeve is relatively fixed, the anchor rod at the rock wall is free relative to the rock wall of a roadway and moves towards the interior of the roadway, the rod body also moves outwards, the rod body moves to trigger the compression device to compress the compression body, and the compression body exerts force on the outer wall of the sleeve. The position o
