  4. Abstract : incompatible element nh11 and hybrid stress element 18 were employed to analyze rock burst occurring in coal face 9108 of sanhejian coal mine. compared with the results from ansys, the two optimized fems can execute more accurate numerical simulation in the research of rock burst as well as other rock problems and lessen the errors from inaedquately meshing in huge calculations due to the limitation of labor and computer time. in addition, the criterion of averaged generalized stress rate was proposed and used to determine the site and moment of rock burst. the given conclusion is in accordance with the face of coal face 9108 very well
