| Abstract: | The counter analysis methods, mathmatical model, optimization mothod, binding conditions of the stope country rock property be discussed in detail.
In basis on the finite elements and Nelder-Mead optimization method with binding conditions and theory heard and measured displacement. The rate of stope rock mass and rock lump in Long Feng coal mine -635 level is 0.52; variations of laws of mining face front coal mass property be obtained. |
