Assessing of damage zone in the vicinity of blasting, is one of the very important issues in mining projects, tunnel and underground spaces, construction of dam and high structures. Damage zone induced by explosion around blasthole consists of crush and crack zone, where radial cracks exist in crack zone. From the point of view of blast designing, determination of characteristics and boundary of damage zone is very important. Physical and mechanical properties and seismic wave velocity between damage and intact zone of rock are different. In this research, depending on laboratory experiments on rock samples before and after detonation, the influence of explosion on physical and mechanical properties of rock and damage zone has been evaluated. For this purpose, six cubic samples of marble with 30*30*30 cm in dimensions have been selected. Characteristics of marble samples like longitudinal and shear wave velocity, physical properties, slake-durability index, tensile and uniaxial compressive strength before and after detonation have been measured. In addition, the correlation between longitudinal wave velocity, shear wave velocity, Poisson's ratio and dynamic elasticity model's has been evaluated. Intactness index (K v ) has been used in this study for the assessing of damage zone after detonation. Longitudinal wave velocity and intactness index fields before and after detonation have been represented by gradient colors and contour lines. The effect of damage ratio induced by explosion on physical and mechanical properties of marble samples has been assessed. It found that tensile and uniaxial compressive strength after detonation in comparison with before detonation have been decreased. Furthermore, the influence of displacement rate on the results on uniaxial compressive strength and elasticity module's has been evaluated. Results indicate that with increasing of displacement ratio, compressive strength and elasticity module's have been increased.
