Taking the 3305 working face ,in Wuyu Colliery as the research object ,the author studied and ana-lyzed roof breaking regularity at large mining height working face of soft coal seam by numerical simulation and field measurement ,mastered roof breaking regularity such as the step of initial pressure ,the step of period pres-sure and growth characteristics of three zones at large mining height working face of soft coal seam ,which pro-vided some reference value for post -mining work .
