采动岩体裂隙形成、扩展和分布均十分复杂，而初始结构面的存在使其更加复杂。本文借助相似材料模型实验，模拟了结构化岩体采动裂隙的分布规律，应用分形几何理论研究采动岩体裂隙分布的自相似性。研究表明：具有初始结构面的岩体采动后形成的裂隙网络具有很好的统计自相似分形性质，分形维数可以综合描述采动岩体裂隙化程度，且地表沉陷特征值与分形维数具有明确的数量对应关系。
The formation, propagation and distribution of the fractured rock mass in mining are all very complicated, while the existence of the initial structural plane makes it more complicated. In this paper, similar material model experiments are used to simulate the distribution of structural fractures in fractured rock mass. Fractal geometry theory is applied to study the self-similarity of fractured rock mass distribution. The research shows that the fractured network formed by the mining of the rock mass with the initial structural plane has a good statistical self-similar fractal property. The fractal dimension can comprehensively describe the degree of fracture of the mining rock mass, and the eigenvalue of the surface subsidence and the fractal dimension Has a clear number of correspondence.
