尾矿坝坝体在自身和外界因素的影响下发生大的变形与压缩时,会严重影响坝体的稳定性,而尾矿特性如压缩性、膨胀性等,能够通过液限特性来表征,为此,研究通过液塑限联合测定试验测定尾矿液限值,并找出不同粒径的尾矿对尾矿液限的影响。试验表明:0.025 mm是一个分界值,其中小于0.25 mm以下的尾矿含量与液限值呈现较好的正相关性,0.075 mm以下的尾矿砂对尾矿的液限的影响最为明显。
Tailings dam body deformation and compression under the influence of its own and external factors, will seriously affect the stability of the dam, and tailings characteristics such as compressibility, expansibility, etc., can be characterized by the liquid limit characteristics, To this end, the study determined by liquid-plastic limit test determination of tailings limit, and find out the tailings of different particle size of tailings liquid limit. The experimental results show that 0.025 mm is a cut-off value, and the tailings content below 0.25 mm has a good positive correlation with the liquid limit value. The tailings with the diameter below 0.075 mm have the most obvious impact on the liquid limit of the tailings.
