Problems solved by technology

However, although the existing roadway support devices have strong supporting strength, they are prone to deformation when the impact rock pressure comes, and then weaken or lose the corresponding supporting performance, resulting in serious deformation or even closure of the roadway

Abstract

An embodiment of the invention discloses a scour prevention and support device for a roadway, relates to the technical field of civil engineering, and can effectively improve the support performance.The scour prevention and support device for the roadway comprises a first support layer and a second support layer, wherein the first support layer and the second support layer are stacked and connected to each other; a shrinkable portion is provided in the first support layer, and the shrinkable portion can be deformed by absorbing stress energy when the stress borne by the first support layer exceeds a first threshold. The scour prevention and support device can be used in the field of coal mining.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a roadway anti-scour support device. Background technique [0002] Rockburst is also called rock burst disaster (bump disaster). It is called coal burst in coal mines. It refers to the destruction of the balance state of the ore body or rock mass under the action of internal high stress, and the sudden release of a large amount of energy, resulting in explosive vibration. , and disasters caused by the sudden eruption of ore bodies and rocks around the shaft. [0003] With the transfer of coal mining to deep areas, the problem of rock burst disasters has become more serious and prominent, and as a special form of mine pressure, it has become the main disaster in deep mining mines and seriously threatens the safe production of coal mines. [0004] As an indispensable and important content in the prevention and control of rock burst, anti-scour support is the last barrier...
