土壤固化剂在尾矿干堆适用性试验研究

为了探究不同类型土壤固化剂在尾矿干堆应用的可行性，选取了有机类（A:环氧树脂E51+环氧树脂固化剂W93与B:环氧树脂E51+环氧树脂固化剂T31）、无机类（C:水玻璃+氯化钙与D:水玻璃+五水硫酸铜+硫酸铝钾）与生物酶类（E:FRT与F:DS）固化剂开展室内试验，对固结后的硬度指标进行测试，并对固化剂的抗高温性能、抗风性能与抗水性能进行试验研究。结果表明:喷洒固化剂的砂模表层会形成一定硬度的壳体；所有固化剂的抗高温效果良好；喷洒了C、D固化剂的砂模在风吹后的质量损失率较其余固化剂的大；B、F的抗水性能在所有固化剂中的效果最好。

Experimental research on applicability of soil stabilizer in dry-tailing stacking

In order to study the feasibility of applying different types of soil stabilizer in dry-tailing stacking, several stabilizers of organic(A: epoxy resin E51+ epoxy resin curing agent W93 and B: epoxy resin E51+ epoxy resin curing agent T31), inorganic(C:sodium silicate+ calcium chloride and D: sodium silicate+ copper sulfate pentahydrate + aluminium potassium sulfate) and biological enzyme(E:FRT and F:DS) were chosen to carry out laboratory test. The hardness indexes after curing were tested, moreover, the performance of wind-resistance, water-resistant and high temperature-resistant were researched. The results showed that the surface of sand mould being sprayed by stabilizer formed a shell with a certain hardness, and the high temperature-resistant performance of all stabilizers were fine. After wind blowing, the mass loss rate of sand mould being sprayed by stabilizer C and D were larger than others. The water-resistant performance of stabilizer B and F were the best in all stabilizers.
