The waste dump of open-pit coal mine is remade of soil-rock mixture under the action of gravity, dynamic load of transportation equipment and earthquake, etc. By using artificial synthetic transparent soil, the developing process and migration law for soil-rock mixture are observed in the remade process. The mixture of fused quartz sand, liquid paraffin and n-tridecane is chosen as the material for synthetic transparent soil which is mixed with liquid paraffin and n-tridecane at a mass ratio of 4.4 at room temperature of 17℃. Physical and mechanical properties of transparent soil are determined by physical test and compared with those in natural sandy soil. The results show that transparent soil and sandy soil have high similarity, in other words, transparent soil can be used for similar simulation experiments of soil-rock mixture.
