Laws of water runoff and sediment yield on the disturbed lands resulted from the exploitation of Shenfudongsheng Coalfield were investigated by using field water discharge scouring experiment.The results were follows.(1)No correlations were fould between degrees of slope and average water runoff time and amount.A power function relations existed between the average water runoff time and flow discharge(t=20.18Q-0.571,R2=0.84),second-order relationship existed between the average water runoff amount and flow ...
