摘要
尾矿的物理力学性质如干密度、强度等与其堆存深度关系的密切程度与一般的土有较大的区别。对广东省大宝山槽对坑尾矿库尾矿料进行的物理力学性试验研究中,得出了e p曲线拟合幂函数方程以及尾粉砂内摩擦角和孔隙比的关系。研究表明,各种尾矿都具有一定的凝聚力。控制尾矿排放工艺,改善坝体的排水条件是增强坝体的稳定性的必要条件。
The tailing is different from common soil in the relation of the physical and mechanical properties (such as dry density and strength) with the stockpiling depth. Based on the experimental studies of the tailings from Dabaoshan Mine of Guangdong, the e-p curve fit power function equation and the correlation between the internal friction angle and the void ratio of silty tailings was found. The results show that all tailings have certain cohesion. An appropriate technique for tailing discharge and better drainage conditions are indispensable for the enhancement of the dam.
