摘　　要：为深入认识潘北矿11113工作面A组煤底板岩体结构特征,运用分形理论对其断裂网络复杂程度进行研究并计算断裂分维值。研究表明:A组煤底板岩体结构主要为块裂结构和碎裂结构,且范围较大;松散结构及碎裂结构主要集中分布于断层发育区。In order to deeply understand the structural characteristics of the coal floor rock mass of Group A of 11113 working face in Panbei Mine,the fractal theory is used to study the complexity of the fracture network and calculate the fracture fractal dimension.Research indicates that the rock mass structure of group A coal is mainly composed of block-fracture structure and fragmentation structure,and the range is large;loose structure and fragmentation structure are mainly distributed in the fault development area.
