摘　　要：分别进行沉降实验和流变学实验,以便更好地了解尾矿的沉降特性及其流变学特性,进而得到尾矿的沉降规律以及尾矿屈服应力与其固体浓度的关系,并利用数值拟合得到固体浓度和屈服应力的自定义模型。结果表明尾矿沉降的初始阶段,其沉降速度较大,沉降明显,尾矿的屈服应力随着固体浓度的增加而增大。To understand the settlement characteristics and rheological properties of tailings better,sedimentation experiments and rheological experiments are carried out.We can obtain the law of tailings settlement and the relationship between the yield stress of tailing and its solid concentration,and get a custom model of solid concentration and yield stress by using numerical fitting technology.Results show that the initial stage of tailings deposition sedimentation velocity is larger and the subsidence is obvious,the yield stress increases with the increasing of tailings solid concentration.
