| Abstract: | In this paper, the structure mechanics model of the main roof consisted of many beams was established based on the research of the equivalent material model and the practised experiences. The mechanical relationship between the face supports and the whole movement of the main roof beams was analysed carefully. The interaction equation describing the relationship between the suppors and the main roof, when the upper beam of main roof is under "Granted Deformation" condition, was established. Moreover, the auther revealed the basic principle of designing the face supports |
