The method of measuring discontinuous deformation of steep coal seam mining is proposed. The finite element method is used to analyze the influencing factors of discontinuous deformation of surface under the condition of inter-layer weakness. The discontinuous deformation of ground surface caused by mining of steep coal seam is analyzed. Surface location, weak face width and weak face medium.An example analysis shows that the calculation method is simple and effective and provides a new way to calculate discontinuous deformation of the ground surface.
