Hydrogeology Response to the Coordinated Mining of Coal and Uranium: A Transparent Physical Experiment by Tong Zhang, Xiang He, Kai Zhang, Xiaohan Wang, Yang Liu

“…The vertical leachate infiltration of 4.83 m was observed in the scenario of uranium mining prior to coal, which is smaller than those in the scenarios of comining of coal and uranium (10.26 m) and coal mining prior to uranium (16.09 m). A slight strata movement below the uranium was observed, and the leaching solution infiltration in the coal mining area was not observed in a short period in the scenario of uranium mining prior to coal; both of those was presented in the scenarios of comining of coal and uranium and coal mining prior to uranium.…”
