中文摘要：

以11届国际岩石爆破破碎会议论文为参考,结合国内近3 a来的研究成果,归纳总结了国内外研究者在岩石爆破破碎理论、爆破块度模型及分布函数分析、岩石爆破破碎数值计算和岩石块度测量技术4个方面的研究成果。分析讨论了国外学者在矿山岩石爆破破碎领域的研究动态和未来发展趋势,认为在矿岩爆破破碎的理论研究方面,我国具有领先优势,在爆破块度模型及统计函数研究方面的创新意识明显,但在数值软件开发与图像处理等自动化、智能化方面还存在差距。期望讨论结果能为我国的科研工作者以及技术人员在矿岩爆破破碎、爆炸能量利用与矿岩高效开采研究方面提供有益参考。

英文摘要：

According to conference papers of the 11 th International rock blasting fragmentation,combined with the domestic research results in recent 3 years,research results are summarized from four aspects of theory of rock blasting fragmentation,block model and distribution function,rock blasting numerical calculation and rock block measurement technology. The research dynamics and foreign research trends in the field of blasting fragmentation are analyzed and discussed,and the results show that China has obvious advantages in the field of ore rock blasting theory research,and has innovation consciousness in the blasting fragmentation model and statistical function,but we have a long way to go in the aspect of numerical software and image automation and intelligent processing. The discussions in this paper aim to providing reference for our scientific research workers and technicians in the ore rock blasting fragmentation,utilization of explosive energy and high efficiency mining of ore rock.
