Geomechanics model test can simulate the real excavation process of geotechnical engineering and the mechanics deformation properties of the rockmass prototype on the condition of meeting the similar principles. In order to conducting geomechanics model test, similar material which can meet similar mechanical properties must be used. It is only after conducting a massive mechanics experiments that a new-type similar materials called iron crystal sand is developed in this paper. This material consists of iron ore powder, blanc fix, quartz sand, gypsum powder and rosin alcohol solution which are evenly mixed in certain proportion and pressed together. The iron ore powder, blanc fix and quartz sand among them are main materials. The rosin alcohol solution is the cementing agent and gypsum powder the regulator. The material mechanics experiments show that this material has following outstanding characteristics: high volume-weight, wide variable mechanical parameters, stable performance, low price, quick drying, simple processing and innocuity. It can simulate most rockmass material from soft to hard ones and can be widely used in geomechanics model tests in fields of energy sources, transportation, water conservancy and mining.
