Abstract: An accurate grasp of cavity shape, size and its change is the key to the cavity stability numerical simulation. The basic components, principle and monitoring way of CMS are introduced. In this paper, on the basis of the actual situation of Donggua Shan Copper Mine, the cavity model and geological model of the mine are constructed by using the Surpac software based on CMS. A method of constructing numerical computing model with the coupling of Surpac and Phase2 is put forward. The simulation calculation is carried out. The stability of cavities surrounding rock mass is analyzed according to the simulation calculation results. The research shows that the combination of the advantages of CMS, Surpac and Phase2 provides a new and effective way for numerical simulation research on the stability of rock engineering.

Key words: cavity, modeling, cavity monitoring system, Surpac, numerical simulation
