摘　　要：爆破块度的预测与控制一直是岩石爆破破碎领域的重要课题。岩石爆破涉及爆炸冲击波和爆生气体的联合作用以及岩石破碎、抛掷和堆积复杂过程,通过岩石爆破破碎过程模拟、定量计算爆破块度至今仍未实现。针对岩石爆破破碎机理和力学模型、岩石爆破破碎过程数值模拟方法和岩石爆破块度的预测模型的国内外研究现状和进展进行了全面综述,并对岩石爆破破碎模拟和块度预报领域有待进一步研究和突破的重点问题进行展望。The prediction and control of blasting fragments has always been a significant topic in the field of rock blasting.Rock blasting involves the combined action of explosive shock wave and explosive gas,as well as the complex process of rock fragmentation,throwing,and piling.Therefore quantitative simulation of rock fragmentation and calculation of blasting fragments has not been achieved till today.The research status and progress of rock blasting breakage mechanism and mechanical model,numerical simulation method of rock fragmentation by blasting and prediction model of rock fragments are reviewed,and the key problems in the field of rock blasting simulation and fragment prediction are forecasted.
