In order to analyze the influence of lateral abutment pressure of goaf to No.2307 Face of Xiaoyun Mine, a 3D numerical model was constructed by using FLAC3D numerical simulation software, and the distribution characteristics of coal pillar stress were analyzed. The results showed that the No.2307 track roadway was mainly affected by the lateral abutment pressure of No.1308 goaf during excavation, but the stress concentration coefficient was less than 1.5 in the area where the lateral abutment pressure of No.1308 goaf was reduced. Subsequently, large-diameter drilling was adopted to prevent rock surge, and realized the safe excavation of No.2307 track finally.
