摘　　要：随着仪器科学、测试技术和爆破领域相关交叉学科的跨越式发展,岩石爆破基础理论研究取得了丰硕的研究成果,为工程爆破技术开发和应用提供了科学指导。提出了岩石爆破基础理论研究的2个关键科学问题,即:炸药爆炸做功与岩体破碎耗能的耦合作用机理、炸药能量释放与爆炸裂纹扩展的精细控制原理。指出以岩石本构关系、动静关系、波纹关系和损伤评价为主线的系列研究是解决关键科学问题的具体途径,系统梳理了现阶段岩石爆破基础理论的研究进展。在此基础上,提出了3点研究展望,即:岩石爆破内部三维裂隙场的实时监测、考虑爆破物理过程的数值仿真算法、围岩爆破损伤的精准评价。With the leapfrogging development of instrumentation science,testing technology,and related interdisciplinary fields in blasting,the fundamental theory of rock blasting has achieved fruitful research results,providing scientific guidance for technological development and applications in the field of engineering blasting.Two key scientific issues were raised in the fundamental theoretical research of rock blasting:the coupling mechanism between the work done by explosive detonation and the energy consumption of rock fragmentation,as well as the fine control principle of explosive energy release and blast crack propagation.It points out that a series of studies focusing on“three major relationships”and“one evaluation”are specific approaches to address the key scientific issues,systematically reviewing the current research progress of the fundamental theory of rock blasting.On this basis,three research prospects are proposed:the real-time monitoring of the internal three-dimensional fracture field during rock blasting,the numerical simulation algorithm considering the real physical process of blasting,and the accurate evaluation of rock blasting damage.
