%X The technique of gob-side entry retaining in fully-mechanized coal face with top-coal caving is the key measure with which the Y type ventilation manner can be used to solve the problem of face gas accumulation. According to the given conditions of Changchun Coal Mine,Luan Bureau,the equivalent material simulation testing is made,and the broken situation and shape of main roof,the influence of different support on roof activity are analysed. The study results provide scientific basis for the determination of the support of gob-side entry and the parameters of roadside filling.
