摘　　要：岩体多属于各向异性的复杂不连续体。岩体中主要结构面在爆破时,会对岩石的破坏和最终的爆破效果产生影响。总结了结构面岩体爆破破坏机理的研究现状,并从应力波传播、岩体破坏方式等方面研究了结构面岩体爆破的影响。在研究结构面岩体爆破破坏作用机理的基础上,提出改善爆破效果的技术措施,供同类型矿山参考。Most of rock masses belong to anisotropic complex discontinuous bodies. When blasted,the main structural surface in the rock mass will impose an impact on the rock damage and the final blasting. The paper summarized the current research status of structural face rock mass blasting damage mechanism and from the aspects of stress wave propagation and rock damage manner,studied the influence of structural rock mass blasting. Based on the study of structural face rock mass blasting damage mechanism,technical measures to improve blasting effect were proposed,providing reference for similar mines.
