Abstract: The supporting method of three soft narrow coal pillar gob-side entry driving has been used to symmetrical support, while the damage of roadway often appears asymmetric deformation characteristics; the support technology of gob-side entry driving meets great challenge, and the damage law is extremely complex. This paper takes Micun Coal Mine 210101 roadway head as an example, analyzes the asymmetric deformation characteristics of roadway and establishes anchor net supporting plan of 210101 roadway head. The test result shows that roof-to-floor convergence is between 0.32 m and 0.37 m, two-sided displacement is between 0.21 m and 0.28 m, and the data of roof separation is between 0 to 50 mm. The roadway surrounding rock deformation has been effectively controlled.
