Abstract: For complex fault network, a new path cut algorithm was proposed, by which all types of complicated fault intersection can be dealt with, such as Y, λ, X, half-Y, half-λ contact relations. This fault modeling method not only avoids the limitation of the Pillar method and binary tree method, but also greatly improves the flexibility and accuracy of fault modeling. The method improves semi-automatic processing of the contact relationship between faults and quick updating of fault models. Through the validation of practical model, the modeling of complex fault network can be successfully and quickly solved, and the efficiency of modeling was also greatly improved.

Key words: fault networks, contact relationship, path-cut algorithm, binary tree, Pillar method
