摘要：

The comprehensive understanding mechanism of large deformation of mine roadway in weak rocks will lead to design support system both more safely and economically. In this paper, the mechanisms related to the large deformation and failure of roadway excavated in soft rock mass are discussed, a quantitative relationship between the deformation of surrounding rocks and the support pressure of roadway is proposed on the basis of field investigations and laboratory tests.
