Abstract: In view of the difficulties of surrounding rock control in gob-side entry retaining under thick coal seam in Gaohe coal mine, the main deformation characteristics of the surrounding rock were analyzed. The top coal and the coal pillar were cut severely, and the crushing deformation was large. The numerical simulation was used to compare the mechanical parameters of different filling bodies and the surrounding rock response under the support strength. Based on the previous test experience, the width of backfill was 1.5 m and compressive strength was 30～35 MPa. Inside the roadway high pre-stress and intensive support with cable bolts in pillar side should be applied. Flexible template and high pre-stress and intensive support of gob-side entry retaining were tested in E1302 and W1309 mining face. The monitoring of filling body stress, anchor stress and single hydraulic prop stress and surface deformation showed that stability of surrounding rock was ensured by comprehensive technology and the initial success of the lane was achieved.
