Description

Technical Field

[0001] The utility model relates to the technical field of rock burst protection devices, in particular to a mobile multi-stage arch combined structure rock burst protection device. Background Art

[0002] Rockburst, also known as rock burst, occurs when the previous rock stress balance system is broken due to the artificial disturbance of cavern excavation under the action of high ground stress. High horizontal stress accumulates in the section of the cavern surrounding rock due to stress redistribution, causing a large amount of energy to accumulate in the local area of ​​the surrounding rock in a short time. When the accumulated energy in the rock greatly exceeds the energy required for rock destruction, the rock mass undergoes strong rock ejection destruction, and the accumulated energy is released in the form of kinetic energy. It is an extremely destructive geological disaster caused by dynamic instability of the surrounding rock.

[0003] In order to avoid casualties of workers when a rock burst occurs, a rock burst protection device is needed to ensure the safety of the workers. However, the rock burst protection device is set on a slide rail and can only move on the slide rail, which is quite limited.
