The invention discloses a method for judging the rock burst proneness of a rock material. According to the method, the dissipated energy required by burst of rock is calculated according to a stress-strain curve after the rock reaches the peak intensity; due to a one-off loading and unloading experiment on a rock test sample, a real series value (Ki) and a ratio (lambda(i)) of the elastic strain energy to the total input energy before the rock reaches the peak value are in linear relation, so that the ratio (lambda(i)) of the elastic strain energy to the total input energy when the rock reaches the peak intensity, and the total input energy U1 at the peak intensity of the rock can be calculated according to the stress-strain curve, so as to obtain the elastic deformation energy at the peak intensity of the rock. Therefore, the problem that the elastic strain energy stored therein cannot be calculated as the rock under the peak intensity cannot be unloaded in time is solved; the calculated elastic strain energy is compared with the post-peak dissipated energy to judge whether the rock material has the rockburst proneness. The invention provides a brand-new judgment method for determining the rockburst proneness of the rock material.
