Abstract

The invention provides a mine support structure, and relates to the technical field of mine safety. The mine supporting structure is arranged at the top of a mine main withdrawing rack, a plurality ofanchor rods are distributed in an array in the first preset direction and the second preset direction of the top of the main withdrawing rack, and each anchor rod extends upwards from the top of themine main withdrawing rack. A plurality of anchor cables are distributed in an array in the first preset direction and the second preset direction of the top of the main withdrawal rack, the multiplerows of anchor cables are alternately distributed with the multiple rows of anchor rods, and each anchor cable extends upwards from the top of the mine main withdrawal rack. At least one row of anchorcables located in the middle of the mine main withdrawal rack and at least one row of anchor cables near the non-mining side extend upwardly at an oblique non-mining side 40-50 degrees. The mine supporting structure can enable the top plate to be in a high pre-tightening force state, so that the possibility that the top plate at the upper side of the non-mining side is broken is reduced; and forthe top plate of the supporting section, fracture is not prone to occurring, and therefore the centralized pressure concentration of the lower withdrawing rack and the potential safety hazards of thesupport and equipment of the lower-level rack way can be avoided.

Description

technical field [0001] The present application relates to the technical field of mine safety, in particular to a mine support structure. Background technique [0002] Under normal support conditions, it is easy for the mine to break directly above the non-mining side, resulting in concentrated pressure in the lower roadway, which poses a very large safety hazard to the support, equipment and staff of the lower roadway. Contents of the invention [0003] The purpose of the embodiment of the present application is to provide a mine support structure, which can improve the technical problem of the fracture directly above the non-mining side of the mine, resulting in the concentration of pressure in the lower withdrawal roadway. [0004] In the first aspect, the embodiment of the present application provides a mine support structure. The mine support structure is arranged on the top of the mine main withdrawal roadway. The first preset direction along the side of the mining s...
