描述了孔边线状裂纹扩展的断裂控制过程。建立了控制爆破参数与岩石强度、断裂韧度和炸药性质等之间的关系。得出了尽可能加大炮孔间距的合理尺度。
The fracture control process of linear edge crack growth is described. The relationship between controlled blasting parameters and rock strength, fracture toughness and explosive properties was established. Obtained as much as possible to increase the distance between the gun hole reasonable scale.
