摘要(Abstract):
岩体爆破机理研究工作开展的十分艰难,现有的主要理论均不能全面彻底地解释岩体爆破中的现象、描述岩体的破碎过程。而几乎所有的理论都是从岩体出发来展开研究,忽略了对炸药作用的研究。总结前人在岩体爆破破碎机理研究上的学说、论断、论点,结合爆破实践,以炸药作用为出发点,提出传爆点振效应破岩机理,且按照作用源划为三类破岩模式。并尝试用该理论来解释岩体爆破中的各种现象,更加有效、充分、客观地揭示岩体爆破破碎机理的物理实质。
The study of mechanism of rock blasting fragmentation is very difficult.The exiting mechanisms can not explain the fragmentation phenomena or describe the fragmentation process comprehensively or thoroughly.Almost all of the exiting mechanisms were obtained by studying the rocks,few mechanisms were obtained by studying the effects of explosive.Previous researchers′theories and judgments on rock fragmentation mechanism by blasting were summarized.Combining with blasting practice and taking the effects of explosive as starting point,the point vibration effect mechanism was proposed to try to explain the phenomena in rock fragmentation by blasting.The theory was divided into three kinds of rock fragmentation model according to contributing source.It was more effective,sufficient and objective to reveal the essence of rock fragmentation by blasting.
