摘　　要：描述了目前国内外学者对节理岩体爆破的研究进展，分析了常用的一些数学模型，阐述了人们对爆破块度的测定及预报情况以及计算机模型模拟及其应用。节理岩体本身的特性较一般工程材料更复杂、更特殊，因此在爆破作用中，节理对爆破效果的影响有时比岩体本县物理力学性质的影响更显著，所以研究更有理论意义和实际意义。文章提出了节理岩体爆破的研究工作中今后需要解决的一些问题。The present development of study on jointed rock mass blasting by scholars all over the world are described and some common mathematical models are analyzed in this paper.The determination and prediction of blasting fragmentation,computer model simulation and its application are discussed.As the characteristics of jointed rock mass are more complicated and special than common engineering materials,the joints are more important than the physical characteristics of rocks in blasting. So this study has more theoretical and practical significance.Finally,some problems needed to be solved in the future are put forward.
