Abstract Based on the engineering support of coal mine 8711 working face of the state of numerical simulation methods, the research of typical thick coal seam roadway surrounding rock stress and roadway destruction and deformation characteristics were conducted. According to the research, which put forward anchor steel band, anchor cable with large tray for roadway supporting design scheme and based on the roadway surface convergence monitoring results, summarizing the typical roadway deformation law of mine pressure monitoring showed that the reliability of the research and design.
