A face bolt is normally horizontally installed. However, it often deviates from the initial horizontal position. The reinforcement effect of face bolts by its installation angle is analysed in this study. For the purpose of preventing surface subsidence and horizontal displacement of face, the face bolt should be installed as horizontally as possible, and if it deviates from the initial position, more bolts should be installed. Also, the residual face bolt left behind the face due to its installation angle has little supportive effect because it its too short and radially arranged.
