ABSTRACT

Rocks mass of roadway in deep mine show soft behavior because they are located in high stress environment. Due to its larger cross section and complex geometries deformation of floor around roadway intersection is usually greater than roadway doesn’t intersect. Floor heave has a great influence on ventilation, transportation, and so on, thus a lot of literatures already exist about this issue, but there are only a few in which was based on alternating effects between softening and creeping (Yang et al. 2006).
