中文摘要：

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。

英文摘要：

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.
