Through the observation and research of 197 individuals (male186, female 4 and minor 7), the authors found that trauma caused by violence on the remains of dead miners shows a certain rate. A total of 40 individuals shows the traumas while 70 cases have been found. This paper combed the predecessors' study of bone trauma history. By using forensic traumatology research methods,trauma types and sizes were observed and measured. The authors also analyzed the location of the batter, the strike direction and handedness when the injury happened and classify the traumas. Statistical analysis shows the distribution of trauma in different groups, the proportion of all kinds of trauma appeared, and in the distribution of trauma and the degree of damage. The study shows that the puppet army ruler persecution for miners has been extended to women and children. Most of traumas found in remains were caused by effective struck tools such as swords or hammers violently blow to the skull face to face. And the striker armed at greater risk of left hands.
