| Abstract: | The article adopted The WilianmWarnke strength failure criterion for predicting the failure of brittle materials the and used the function of "element is killed dead" in finite element method to simulate mining process. The investigation of rockburst prevention and its numerical simulation in slant coalbed were carried out, revealing the law of stress field and deformation field and the liberating degree and scope in extracting release coalbed .The results provided important basis for rockburst prevention. |

| Keywords: | extract release coalbed change of element state strength failure criterion |
