To master the law of surrounding rock activity in gob-side entry retaining, and roadside filling body stress and deformation and analysis the effect of gob-side entry retaining. This paper monitors roadway deformation, roof separation and the force of the bolt during gob-side entry retaining; The observation results show that gob-side roadway is stable, good support effect and can meet the needs of production during entry retaining.
