摘　　要：利用分形理论对唐山矿南五区的断裂网络复杂程度进行了评价,即所算得的分维数越高,则构造越复杂,对矿井的安全生产影响就会增大。研究表明:从5#煤层至9#煤层,断裂迹线分布程度从集中到相对分散;构造复杂区主要位于区域北部及南偏东位置,而该区中部偏东位置和西南角的构造简单,相对稳定。In this paper,the fractal theory is used to evaluate the fracture network complexity of Nanwu section in Tangshan mine.The higher of the calculated fractal dimension means the more complexity of the mine structure,which will increase the influence of mine safety production.The result shows that the fracture tracing line is scattered from a centralized distribution degree from the fifth coal seam to the ninth coal seam.The complex structure areas are mainly located in the direction of North and South by East,but the East by middle direction and Southwest corner of Nanwu section have relative simple and stable structure.
