摘要
以云南某实际尾矿库为例,利用颗粒流离散元法和MatDEM软件建立完整的三维实际地形,并对尾矿库溃坝及尾砂下泄演进过程进行模拟,研究尾砂浆的锋面速度、分布形状、淹没范围等规律。研究表明,基于颗粒流离散元法与实际地形条件下模拟的尾砂浆运移溃坝过程更真实、贴合实际。
Taking an actual tailings pond in Yunnan Province as an example, a complete three-dimensional actual terrain is established by using particle flow dispersion element method and MatDEM software, and the evolution process of dam break and tailings discharge of tailings pond is simulated to study the laws of front velocity, distribution shape and inundation range of tailings mortar. The results show that the dam break process based on the particle flow dispersion element method and the simulated tail mortar movement process under the actual terrain conditions is more real and practical.
