| Abstract: | The prediction of displacement rate in surrounding rock of face entries is amain link of the entry supporting design. This paper,based on the major factors affecting thestability of face entries,analysed and sorted out the observation data of more then 100 typicalentries By using polybasic regression method,we derived a set of regression equations used topredict the displacements in the surrounding for all kinds of roadways.It has been verifed bytheories and examples that this kind of forecasting method has extensive and practical valuein the supporting design of face entries. |
