A BREIF OF CENTRIFUGAL MODEL TEST AND ITS APPLICATION TO COAL MINE

Centrifugal Model Test (CMT)is playing a more and more important role in engineering construction nowadays beacuse it can simulate the self-gravity stress field directly. In this paper, the fundamental principle, the characteristics and the current status of CMT is briefly introduced, then its application to coal mineis discussed in detail. Furthermore, the process of coal mining is simulated with CMT. Finally the problems existingin CMT are pointed out and the direction for its further development was given.
