The invention discloses a method for estimating the danger degree of outbreak of inrush disaster of a deep tunnel face. The method comprises the steps that an inrush disaster outbreak basic model is established, the longitudinal construction disturbance influence length is determined and corrected according to the actual situation and the danger degree formula of outbreak of the inrush disaster isput forward; and then the water pressure of the forward section, the strength of the surrounding rock, the surrounding rock particle adjustment coefficient, the surrounding rock fracturing degree adjustment coefficient and the data of the distance to the face are acquired through the investigation and the test and the related data are substituted in the formula so as to estimate the danger degree. According to the method for estimating the danger degree of outbreak of the inrush disaster of the deep tunnel face, the danger degree of outbreak of the inrush disaster of the deep tunnel face canbe accurately and reliably
