某排土场抛尾料侧限压缩实验研究

在露天矿山开采中,测试排土场典型土样的力学性质对于露天矿山排土场的安全稳定性设计至关重要。该文对某排土场抛尾料进行侧限压缩实验,并计算相应的压缩指数和压缩系数。实验结果显示,实验土样存在相对较小的压缩性,即受到荷载时的变形较小,可能会导致较小的沉降和变形风险。这些研究结果可以为后续排土场边坡设计提供参考,但仍需要进一步进行综合实验和实地应用,以深入研究实验土样的力学行为和性质。

In open-pit mining,testing the mechanical properties of typical soil samples of dump is very important for the safety and stability design of open-pit mine dump.In this paper,the side-limited compression experiment of the tailings in a dump is carried out,and the corresponding compression index and compression coefficient are calculated.The experimental results show that the test soil sample has relatively small compressibility,that is,the deformation under load is small,which may lead to less risk of settlement and deformation.These research results can provide a reference for the subsequent dump slope design,but further comprehensive experiments and field applications are still needed to further study the mechanical behavior and properties of the test soil samples.
