Abstract Stability analysis of 8110 mining face in Wangzhuang Mine showed that roof with two sides were interacted as a support system to maintain stability of roadway. Based on lower coal strength of two sides in roadway, damage mechanism and destruction form of haulage roadway in 8110 working face were analyzed and researched. According to principle of "reinforcing sides and roof", anchor cable joint support mode was proposed. The practice showed that this support form could maintain stability of roadway, reduce repair rate and ensure the smooth production.
