钼尾矿砂力学性能试验

Mechanical properties test of molybdenum tailing sand

针对河南栾川县某钼矿尾矿料进行试验,根据试验结果统计分析尾粉砂及尾矿砂与黄土混合料的主要物理力学指标,进行击实试验,测定尾矿砂与不同比例黄土混合后,土样的最大干密度及压实性能,并进行剪切试验,探究在不同钼尾矿砂掺加比例的情况下土样的抗剪性能,该试验可供相关钼尾矿砂工程实践参考。

The tailings of a molybdenum mine in Luanchuan County,Henan Province were tested,according to the test results,the main physical and mechanical indexes of tailing silt,tailing sand and loess mixture are analyzed. The compaction test was carried out to determine the maximum dry density and compaction performance of the soil sample after the tailing sand mixed with different proportion and loess. The shear test was carried out to explore the shear resistance of soil samples with different proportion of molybdenum tailing sand.
