An integrated structure-pattern in three-dimensions is established by stereographic projection in order to meet theneeds for study,and the condition and regularity of variation in the three-dimensional pat-tern of rotating echelon fractures are systematically revealed by the simulation of its forma-tion-processes in using a rotating model.
西华山矿脉的三维雁行型式受岩体弧形界面的控制呈有规律的变化，为适应这一研究的需要，采用赤平投影方法建立了完整的三维雁行型式，并利用旋转模型模拟旋转雁行断裂的形成过程，模拟结果系统地揭示了旋转雁行断裂三维型式变化的条件和规律。
