摘要
运用冲击波理论 ,讨论了柱状药包爆破时冲击波对炮孔的扩腔作用和形成的压碎圈大小 ,分析结果表明 ,影响压碎圈半径的主要因素是炮孔尺寸、炸药性质和岩石性质 ,冲击波的扩腔作用主要与炮孔直径和压缩圈半径有关。
Using the shock wave theory, the authors discnss the effect of shock wave on hole reaming and fragment area during cylindrical charge blasting. It is concluded that main factors affecting radium of the fragment area are hold diameter and rock characteristics.
