The simulation results show that the asymmetry structure of the ratchet die cavity influences the BMG's flowing behavior greatly. During the material filling tooth cavity, dead zone volumes exist and situate on the areas with sparse teeth distribution. The full filling or not of the ratchet tooth tips, as the final filling region of the forming process, determines the super-plastic forming quality. Adopting smaller punch speed or longer load holding time is necessary for full filling of the tooth tips.

研究结果表明，棘轮模腔结构的不对称性对材料的流动行为影响显著；在材料向齿形的充填过程中存在流动死区，死区的位置处于齿形分布较稀疏的部位；齿形尖角是成形的最后充填部位，在终成形阶段采用较小的压下速度或较长的保压时间，有利于齿形尖角的完全充满。

The study we have performed demonstrated that the main roof first broke with asymmetry character; gully mining-induced slope was divided into multilateral blocks by surface advance cracks. Furthermore, multilateral blocks rotated and subsided by the function of extrusion and friction between the broken rock block above the goaf and the rock mass advance the coalface.

冲沟坡体下开采时，基本顶初次破断具有不对称性；冲沟采动坡体被地表超前裂隙切割成多边块状，并在两侧坡体的夹持摩擦作用下缓慢回转下沉；相同地质条件下，坡角越大，采动坡体对工作面矿压影响越大。
