Anti-rock-burst supporting frame for mining

Abstract

The invention discloses an anti-rock-burst supporting frame for mining. The anti-rock-burst supporting frame includes a fixed bottom plate, a load-bearing block, a pressure plate, a supporting plate,a buffer plate, rubber plates, an arc-shaped supporting plate and an arc-shaped compression-resistant plate; if impact force generated due to rock burst born by a top plate of a tunnel is born by thearc-shaped supporting plate, the arc-shaped compression-resistant plate and a triangular supporting frame, the pressure is transmitted to the two rubber plates, the rubber plates are deformed to buffer the impact force, and after buffering is performed, the rubber plates are reset; and if compact force generated due to the rock burst born by a side wall of the tunnel is applied to the buffer platethrough anchor rods, the buffer plate moves toward a weighing block after stressed, a first spring and a second spring are stressed and deformed to buffer the impact force, and the first spring and the second spring are reset after the buffering is completed to ensure the stability of the supporting on the tunnel. A better supporting effect can be played on the tunnel, and the impact force can bebuffered when the rock burst occurs, so that the impact on the supporting frame is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a support frame for mining, in particular to an anti-shock ground pressure support frame for mining. Background technique [0002] Rockburst is a major disaster that threatens the safe production of the mining industry. Once rockburst occurs underground, it will cause roadway deformation, roof collapse, bottom drum or support collapse, roadway blockage, and even roof and floor closure, which will cause personal injury to operators, and even Causing fatal accidents, due to the low cost of using wooden sheds, the previous roadway support method mainly used wooden sheds for support, but the support strength of wooden sheds is relatively small, and once the rock burst occurs, the entire roadway will often be destroyed; With the reform of roadway support methods, steel support equipment came into being. At present, this structure is mostly used. This structure can have a better impact effect on the roadway (such as ladder iron shed)...

[0002] Rockburst is a major disaster that threatens the safe production of the mining industry. Once rockburst occurs underground, it will cause roadway deformation, roof collapse, bottom drum or support collapse, roadway blockage, and even roof and floor closure, which will cause personal injury to operators, and even Causing fatal accidents, due to the low cost of using wooden sheds, the previous roadway support method mainly used wooden sheds for support, but the support strength of wooden sheds is relatively small, and once the rock burst occurs, the entire roadway will often be destroyed; With the reform of roadway support methods, steel support equipment came into being. At present, this structure is mostly used. This structure can have a better impact effect on the roadway (such as ladder iron shed), but steel support is in When the rock burst occurs, it is impossible to buffer the rock burst, which will easily cause damage to the support and increase the support cost of the coal mine
