Abstract
Quarry blasting operations are necessary to supply raw materials; nevertheless they produce ground vibration stresses in the foundations of the nearby structures and may affect their stability. Subsequently, estimation of the stress-strain levels can help the engineers to evaluate safety possibilities of the high wall slopes or the nearby structures. In the present study, shallow seismic refraction surveys have been carried out in Bani Khalid quarry to determine the velocity of the compression and shear waves of the quarry area. These seismic wave velocities have been used to identify the dynamic elastic constants such as Poisson’s ratio, modulus of elasticity, and shear modulus. Ground vibration measurements, another set of field measurements, include recording of the three mutually perpendicular components of the peak particle velocities induced by the blasting operations in the quarry. The results of these measurements and calculations have been employed to estimate the normal and shear stresses and strains induced by the quarry blasting operations
