深部岩体爆破理论与技术研究进展与展望:基于中国视角的综述

摘要: 全球浅部矿产资源日趋枯竭,深部矿山开采已成为矿业发展的重要趋势。钻爆法作为深部工程中最主要的开挖手段,在实际应用中仍面临炮孔利用率低、超挖与欠挖严重等突出问题。针对深部岩体爆破开展科学研究,对于深部资源的高效开发与利用至关重要,也是保障深部矿山安全高效运行的基础。本文明确了深部岩体爆破面临的主要挑战,并结合文献计量分析,从理论与技术两个层面梳理了当前研究现状,重点总结了中国科研机构及其代表性研究成果。首先,识别了深部岩体爆破研究的关键发展趋势及主要研究团队;随后,围绕地应力条件下爆炸应力场演化、爆生裂纹扩展行为和深部爆破振动响应特性三大理论方向,综述了相关研究进展,并探讨了掏槽爆破与周边爆破技术在深部岩体中的应用及优化;最后,基于现有研究,提出了深部岩体爆破未来发展的三个重点方向,即深部岩体爆破效果预测、爆破卸荷应力波的形成传播及其协同破岩机制,以及深部金属矿山生产爆破优化。本文旨在为深部岩体爆破领域的后续研究提供系统性的参考与框架。

 

Research progress and future prospect of blasting theory and technology for deep rock masses: A review primarily based on Chinese perspectives

Abstract: Shallow mineral resources are gradually depleting worldwide, therefore, deep mining is becoming increasingly prevalent within the mining industry. Drilling and blasting are the predominant excavation methods used in deep environments. However, challenges such as inefficient borehole utilization and significant over- or under-excavation are frequently encountered. Scientific investigations on deep rock mass blasting are crucial for the effective development and utilization of deep resources, underpinning safe and efficient deep mine operations. This paper identifies the challenges faced in deep rock mass blasting and presents a review of the current research, primarily from the perspective of Chinese institutions and their experiences, integrating theoretical and technical perspectives through a bibliometric analysis. First, key developmental trends and prominent research teams were identified in the context of this review. Subsequently, three principal areas of theoretical research are analyzed and summarized: blasting stress field evolution, crack propagation behavior, and vibrational response characteristics under in-situ stress conditions. The application and optimization of cut and perimeter blasting techniques for deep rock masses were also examined. Finally, drawing upon existing research, this study explores three key future directions: prediction of blasting effects, utilization of unloading stress waves for cooperative rock fragmentation, and optimization of production blasting in deep metal mines. This review aims to provide a systematic framework for future research in the field of deep rock mass blasting.
