摘要
本文详细论述了采场围岩特性反分析的方法、数学模型、优化方法、约束条件等等.依据以上理论与龙凤矿的实测位移,采用有限单元与带约束条件的Nelder—Mead优化方法,得出了—635水平采场岩体与岩块杨氏模量之比为0.52,以及采动引起的工作面前方煤体特性的变化规律.
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.
