卸压孔 meaning in Chinese
pressure relief vent
Examples
- Numerical simulation and industrial test for combined support of pressure - relief boreholes with bolt - mesh in deep coal tunnel
深井煤巷卸压孔与锚网联合支护的模拟与实践 - It is found that the rational located destressing boreholes can induce structural failure of the surrounding rock - mass , consequently the high stress move deeply in the rock - mass , and the stress environment in the surrounding rock is ameliorated , the spatio - temporal order of the destruction of the surrounding rock - mass is changed when the destressing boreholes and bolting net with wire mesh composite support are accomplished , therefore the compound supporting technology has prominent advantage for control the deformation and destruction of the surrounding rock
模拟发现：合理布置的卸压孔可以导致巷帮围岩的结构性预裂破坏，从而使围岩高应力向深部转移；在卸压孔和锚网联合支护后改善了围岩附近的应力环境，改变了围岩破坏的时空次序，对控制围岩变形和破坏具有突出的优越性。
