Abstract: In order to solve the problem of serious damage and difficult control of surrounding rock of gob-side entry retaining filled with narrow high-water material, the strength characteristics of high-water material with water cement ratio of 1.6:1 were tested based on laboratory experiments, according to the engineering background of gob-side entry retaining filled with narrow high-water material in Dengmaotong Coal Mine 2202 face. Based on numerical simulation and field engineering test, the distribution law of deviatoric stress and instability failure mechanism of surrounding rock of gob-side entry retaining filled with narrow high-water material are studied. The results show that: ① with the increasing of the leading face distance, the position of the deviatoric stress peak zone gradually deflects, the magnitude of the deviatoric stress peak gradually decreases, and the closer to the working face, the more severe the mining impact; ② The deviatoric stress peak zone of the surrounding rock of the roadway within 40 m of the leading working face is mainly concentrated in the right upper shoulder angle and the left lower shoulder angle of the roadway. When the distance leading working face is more than 50 m, the deviatoric stress peak zone of the surrounding rock is mainly concentrated in the deep part of the surrounding rock of the roof and floor of the roadway, and is approximately symmetrically distributed; ③ After the mining of the working face and the completion of the gob-side entry retaining, the peak value of the deviator stress of the surrounding rock of the roadway is mainly concentrated at the solid coal wall and the roof at the solid coal wall. During the support, it is necessary to ensure that the anchor cable passes through the position of the peak zone of the deviator stress of the surrounding rock of the solid coal wall and the roof. Based on this, a sub-regional asymmetric combined control technology of gob-side entry retaining with narrow high-water material and dual-roadways is proposed, which is named roof full anchor cable support + three-row single columns in the roadway + solid coal side reinforcement with anchor cable + pre-tightened anchor bolts supplemented with single column wall in roadside high-water material + supported roof by single pillar at the side of goaf and reinforced by anchor bolt. Field engineering practice proves that the control effects of roadway sur-rounding rock is well, and the stability of gob-side entry retaining with narrow high-water material and du-al-roadways is guaranteed.
