损伤模型明确反映了岩石应变率效应及岩石动载破坏的“脆断”和“灾变”特性，并为岩石爆破破碎区的确定和爆破块度预测提供了直接而可行的判据。本文系统介绍了岩石爆破损伤模型的研究进展及成果，指出了其工程应用前景。
The damage model clearly reflects the rock strain rate effect and the characteristics of “brittle fracture” and “catastrophe” of rock dynamic failure. It also provides a direct and feasible criterion for the determination of the rock blasting broken area and the prediction of the blasting fragmentation. This paper systematically introduces the research progress and achievements of the rock blasting damage model and points out the prospect of its engineering application.
