Hydrogeology Response to the Coordinated Mining of Coal and Uranium: A Transparent Physical Experiment

The migration of fracture and leaching solute caused by mining activity is critical to the hydrogeology. To characterize liquid and solid migration in a mining area of intergrown resources, the coordinated mining of coal and uranium was considered, and a physical experiment based on transparent soil...
