Webmetamorphic rocks), when not fractured, typically have very low porosity. A or as part of weathering (e.g. related to pressure release). Strong rocks, like granite or gneiss, may not fracture as easily as weaker rocks, but they can still be sufficiently well broken up to induce significant fracture-related porosity – especially near to surface. WebOct 1, 2024 · The deeply fractured rock mass exists in the environment of in-situ stress and high seepage pressure, and they are prone to seepage-slipping failure. Therefore, it is of …
WebWhen the collapse column of overburden is disturbed by the working face, the grain loss in the karst collapse column occurs by the dissolution and corrosion of groundwater, thereby inducing the water inrush disaster.
