Study on hydraulic properties in a pore-fracture coupled model for predicting water inrush from mine floors
Xiao Zhang
The mining-induced failure zone is one of the main water flow channels. Due to the complexity of fracture distribution and groundwater flow in the fractures, calculating the water conductivity of fractures in the mining failure zone is a hot and difficult research topic at present. In order to simultaneously simulate the permeability of the complete rock mass of the floor and the hydraulic conductivity of the fractures, a numerical simulation model of pore-fracture porous media was established t
