Abstract: Taking the 2101 working face mining roadway of Pangpangta Coal Mine as the research background, the method of topcutting
pressure relief and strengthened support with bolt and anchor cable reduced the stress concentration area, effectively
controlled the deformation of the surrounding rock of the roadway, and guaranteed the safe production.
Key words: top-cutting pressure relief; bolt; anchor cable; strengthened support; stress concentration
