Abstract In order to explore the characteristics of advanced mine pressure behavior of mining roadway in high stress fully mechanized caving face, the mining roadway of 81308 working face in Baode Coal Mine was taken as the research object, and the characteristics of mine pressure behavior of mining roadway were studied by combining numerical simulation with field monitoring. The results show that the 81308 fully mechanized caving face has the characteristics of short weighting step and strong dynamic mine pressure. The peak value of advance stress of mining roadway is about 13.42 ~ 17.0 m ahead of working face; the stress level and surrounding rock deformation of roadway near goaf side are generally greater than those of non- goaf side. The study clarified the characteristics of advanced strata behavior in the mining roadway of high stress fully mechanized caving face in Baode Coal Mine, which provided a theoretical basis for the design of advanced support and the control of strata pressure in the mining roadway, and also provided a reference for the control of strata pressure in the advanced position of the mining roadway under similar conditions.

Key words： high stress fully mechanized caving face numerical simulation characteristics of strata behavior
