摘要针对陕西集华柴家沟煤矿综放工作面现状，对其进行优化设计，使综放工作面设计更加适合该矿开采条件，更好地发挥综放开采的优越性，最大限度地回收煤炭资源。 - Main works : fractal and mechanism of forming fractal of fault surface in rock masses is analyzed and examined with it ' s affect on failure process of mining rock masses ; fractal curves are constructed with matlab to simulate the fault surface . similar material modeling is carried out and the fractal weak - face effect of mining rock masses is studied . mechanics character of rock masses with fractal fault in mining condition is simulated with large finite element software an sys ; catastrophe model of fault activated by mining is constructed with catastrophe theory
主要工作有：检测和分析了岩体断层面的分形性和断层面分形的形成机制及其对采动岩体破坏的影响机理；运用matlab构造了分形曲线来模拟分形断层面，进行了相似材料模拟实验，研究了采动岩体的分形弱面效应；采用大型有限元软件ansys模拟了含有分形断层面的岩体在采动条件下的力学性态；运用突变理论建立了采动断层活化的突变模型。
