Abstract: Taking the floor heave of 11-102 working face in Huipodi Coal Mine as the research background, the similarity simulation
experiment was carried out with the geometric similarity ratio of 1∶200. It was found that the maximum depth of floor failure
usually occurred in the distance between the key layer breaking and the goaf being filled and compacted by gangue. The floor
heave deformation was effectively controlled by using the drilling layout scheme, which provided a guarantee for safe production.
Key words: roadway; surrounding rock stability; similarity simulation; floor heave deformation
