摘要
断裂网络是一种复杂的具有自相似性的分形体系。该文采用容量维研究了安居煤矿一、二采区断裂网络的复杂程度。通过研究表明,断层发育好,分布密集的部位,分维值较大;断层发育不好,分布相应较少的部位,分维值低。根据地质构造分形特征,将研究区分为三个区:构造简单区、构造中等区、构造复杂区。
Fault network is a kind of complicated fractal system having self-similar nature.The paper researched the complexity of the fault network in the No.1 and No.2 section of Anju coal mine using capacity fractal dimension.The research indicated the more developed the faults were and the more closely the faults distributed, the bigger the faults' fractal dimension value was and the fractal dimension value was lesser if the opposite case.Based the geological structure's fractal character,the paper divided the research region into three levels which were easy structure region, moderate structure region and complicated structure region.
