摘　　要：对软岩巷道的底臌特征进行了总结分析,得出某矿软岩巷道的底臌机理及其主要影响因素,针对现场实际提出了加强帮、角的控制可控制巷道底臌的,同时实施底拱可更好的控制底臌,通过现场施工证明,效果较理想。Mechanism and influential factors of floor heave of soft rock roadway are put forward by anaylzing the characteristics and control techniques of floor heave. The stability control of surrounding rock can be improved by reinforcing two side walls and angles. Floor heave would be controlled by inverting arch. The industrial test of this new technique indicates that the deformation of surrounding rocks is effectively controlled.
