Abstract：Based on the concrete block wall of panel 3202 in Dongtan coal mine, and strength calculation of concrete block wall, theoretical calculation and FLAC3D were applied to analyze the surrounding rock deformation and stress distribution, obtaining the support intensity and the stress and deformation of roadside wall in different conditions. According to the analysis, support intensity of concrete block wall meets the demand of gob-side entry retaining in each stage. The study provided necessary basis for rational roadside design.
