· The blasting fracture process of granite specimens can be divided into four different stages, including compressive, crushing, propagating and ultimately failure stages. At the compressive stage, i.e., t = 0 ∼ 7 s, the compressive stress fields are induced by the blasting loads, but no damage occurs around the borehole, as shown in Fig. 9 .
