The invention discloses a method for selecting pressure relief measures according to a pressure relief drill hole deformation mode, and belongs to the technical field of mine dynamic disaster prevention and control. According to the method, an impact force source is judged according to measures such as a deformation mode of a constructed large-diameter pressure relief drill hole, auxiliary slight shock and surrounding rock deformation, and then a reasonable pressure relief measure is selected; and rock burst disasters caused by misjudgment of an impact force source or unreasonable pressure relief mode are avoided. Meanwhile, unnecessary pressure relief measures can be avoided, unnecessary labor force is saved, and the method is used for targeted pressure relief measure construction. And the method successfully judges the impact force source in case application, so that safe recovery of the working face is guaranteed. 本发明公开一种根据卸压钻孔变形方式选择卸压措施的方法，属于矿山动力灾害防治技术领域。该方法根据施工的大直径卸压钻孔的变形方式，辅助微震、围岩变形量等措施，判断冲击力源，进而选择合理的卸压
