The present paper mainly deals with the prediction of blast-induced ground vibration level at Tourah Mine in Egypt. The safe charge of explosive and peak particle velocity (PPV) were recorded for 79 blast events (79 blast data sets) at various distances by using single station seismograph of type REF TEK-130 SMA. These datasets were used and analyzed by the widely used vibration predictors. From the six predictors, vibration levels were calculated and compared with new monitored 15 blast data sets. Again, the same data sets were used to validate and test the three-layer feed-forward back-propagation neural network to predict the PPV. Different propagations equations were derived by using the shapes of the selected predictor's formulae. It is found that among all the predictors, ANN provides very near prediction with high degree of correlation.

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.

Measurements of the seismic wave velocities as well as the density of the rock material are necessary for calculating dynamic elastic constants. Correct determination of the dynamic elastic constants is the base for correct calculation of dynamic strains and stresses. These calculations use equations that haves been formulated according to some assumptions. This study investigates the effect of the assumptions of 1-D and 3-D wave propagation on the magnitudes of the estimated dynamic elastic constants. Also some relations between densities, seismic velocities, velocity ratio, Poisson's ratio, Young's modulus, and shear modulus will be developed. The study depicted a significant effect of the assumption of 1-D or 3-D wave propagation on the calculated magnitudes of the dynamic elastic constants and came up with some useful relationships between the above mentioned parameters.
