Learn MoreThe water-filled karst cave in karst area as the disaster source is the energy storage structure of water and mud inrush disaster. Under the strong disturbance and high water pressure of blasting excavation, the water-bearing cracks in the rock mass between the disaster source and the tunnel face evolve to form water inrush channels, resulting in …
Learn MoreCave ecosystems are characterized by lack of light and, as a result, dependence on connectivity to the surface or internal microbial production for energy supply. Caves are actually part of a larger karst ecosystem that is the entire drainage basin through which moves water, energy and matter.
