Based on the proposed calculation method for determining different dip angle fracture permeability coefficients derived from well flow vibration equation and self-developed slug test system, research in a field fractured rock mass was carried out based underground water sealed cavern project of National Huangdao Petroleum Reserve. The formation lithology site granite gneiss, fractures were not ...

Abstract The next generation of circular high energy collider is expected to be a lepton collider, FCC-ee at CERN or CEPC in China. However, the civil engineering concepts foresee equip these colliders with bigger detector caverns than one would need for so that they can used hadron may installed same tunnel without further engineering. This opens up possibility install extra instrumentation ca...
