| 摘 要： | 利用相似材料模拟实验模拟采动岩体裂隙的形成过程和分布状态，运用分形几何理论研究采空区冒落带、裂隙带和弯沉带岩体裂隙分布的分形规律。实验结果表明：采动岩体裂隙分形维数随开采宽度的增加而增大，岩体碎胀系数、覆岩下沉系数随采动岩体裂隙分形维数的增大而增大。

| Abstract: | By using simulant testing of similar material,the forming process and the distribution status of the cracks in mined rock masses are simulated. The fractal correlation of cracks in caving zone,fractured zone and bend zone in goaf is studied. The testing results indicate that the fractal dimension of the cracks in mined rock masses is enlarged with increment of mining width,and the expansion factor of rock masses and subsidence coefficient of overlying strata become big with increment of fractal dimension of the cracks in mined rock masses. |
