| Abstract: | Gas dead stress is mainly reason for crack occurrence when greater decoupling charge factor is adopted for blasting hole. Calculation methods of crack spread length are investigated by means of stress theory and brittle fracture theory. And law of spead variation is discussed in the crack spread. |
