摘要
应用分形几何学原理和方法,测试分析了大同矿区煤层顶板岩石结构,初步得出碎屑岩粒度、孔隙的分形特征岩石结构的分形维数与抗压强度有很好的相关性,用岩石结构的分形维数认识分析煤层顶板岩石力学性质是一种有效的方法
The structure of roof rocks in Datong mine area are tested based on principles and method of fractal dimension geometry.The size of clastic rock and fractal characteristics of pores are found.There is a good correlation between the fractal dimension of roof structure and compressive strength.The fractal index is an effective method to study the mechanical properties of roof rock.
