| Abstract: |
| An important factor in the open pit pile row tailings is whether the tailings body liquefied, which significantly affects the safety of the open pit to underground mining efficiently. At present, the tailings dam shock liquefaction is researched extensively. While dry stacking body of silt vibration liquefaction is rarely discussed. This paper by relevant test on the tailings, combining microstructure of tailings and engineering experience finds a simple and feasible vibration liquefaction discrimination method. |
