The cause of rockbursts is associated with the variation of the abutment pressure in surrounding rocks. Based on the case of the LW1301 in Yuncheng Coal Mine，this paper aims to explore the mechanism of the rockburst occurrence under a specific condition of little mining influence. Theoretical analysis，field monitoring，and an engineering test were used to investigate the stress distribution characteristics in the surrounding rocks of a water sump，and their property change. The research work involves：(1) a new rockburst type of static-stress rockburst and its occurrence mechanism. (2) Stress distribution characteristics in the surrounding rocks of the water sump，and (3) the change of the rock and coal property around the water sump through a water immersion test for a month. The study reveals that the rockburst event occurred in the LW1301 in Yuncheng Coal Mine on January 8 is induced by the failure of the weakened coal pillar in the water sump，leading to the transformation of the roof structure and the stress redistribution in the surrounding rocks. The results of this work can provide a reference for rockburst preventions of other longwall panels with similar conditions.
