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