Analysis on the Blasting Stress Wave Spreading Process and Determination on the Blasting Damage and Fracture Criterion of the Bedded Rock

摘要：

The Calculation method and the spreading process of blasting stress wave of bedded rock with cohesion were studied. It is the blasting stress wave which spreading same distance between same medium and different medium attenuation that was compared .The blasting damage calculation method of bedded rock with strongly attached strength was expounded. At the same time, determination on the blasting damage and fracture criterion of bedded rock is discussed.
