Abstract:: On the basis of simulated runoff scouring experiment,the paper deals with the particle movement of the loose mine waste with slope gradient of 20°,25°,30°,35° and discharge of 2L/min,2.5L/min,3L/min,3.5L/min.The results showed that:with the smaller gradient and discharge,the particle movement is characteristic of undulation,randomicity and intermittence,and with large fluctuation of the silt content.The particle movement process can be classified as creep movement、undulation movement and stable movement.With the bigger gradient and discharge,the particle movement is paroxysmal:at initial stage of the experiment,the silt content suddenly reached the biggest point,with the experiment continuing,the silt content gradually deceased and got to a constant finally.The particle movement process can be classified as large scale concentrating movement,cutting downward movement and stable movement.(2) Concentrated overland flow can cause serious erosion,the discharge and slope gradient is a big function of the amount of erosion volume with linear and power relationship.
