文摘This paper theoretically analyzed and discussed the fractures’ initiation, propagation and arrest of grooved borehole blasting under the function of explosion, and provided the optimistic values of blasting parameters. The stress intensity factor and velocity of crack propagation were measured through dynamic caustics measuring system.
