Abstract

Floor heave is one of the main characteristics of deep roadway, once it happens, large deformation in the roadway surrounding rock, especially in road way sides, the normal safe production must be influenced seriously. Research of roadway floor heave mechanism, stress field and displacement field, which are influenced by the dynamic pressure caused by coal mining, is still inadequate. The floor heave is discussed by establishing theoretical model and simulating it. At the same time, taking the surrounding rock as an interrelated whole, reducing deformation stress as research purposes, the main means of preventing tunnel floor heave is by the combined support technology of controlling the roadway deformation and reduce surrounding rock stress.
