Prediction of blast induced ground vibration (BIGV) of,

Efficient prediction of Open Pit mining blast induced ground vibration, has an important role in reduction of the environmental complaints. This paper proposed a new hybrid evolutionary artificial neural network (ANN) optimized by genetic algorithm (GA) to predict peak particle velocity (PPV).Analysis of blasting vibration wave propagation based on,,Explosions induce nuclide vibration on the ground surface, and the vibration intensity of the surrounding medium influences the security of facilities. The dynamic response of the ground surface and the transfer characteristics of the blast waves obtained from the experiment were compared with those from the numerical analysis to verify the accuracy and effectiveness of the numerical analysis.Blasting vibration limits for quarries and civil,,The method for measuring ground vibration is dependent on the blasting application and the type of data that needs to be collected. Velocity is the most common method used to measure ground vibration. This is because it is relatively easy to measure and it is referenced in most relevant legislation and standards.

Safety Distance of Shotcrete Subjected to Blasting,

The drill and blast method is widely used in constructing tunnels in rock. Unfortunately, blasting vibration can damage newly performed shotcrete layers which are major support structures to stabilize surrounding structures. Therefore, investigation of the influence of blasting on shotcrete and determining reasonable distance between blasting work face and shotcrete position is of great,Noise & Vibration Management and Monitoring Plan Yaoure,,Ground Vibration Vibration can be generated within the ground by a dynamic source of sufficient energy, eg a blast. It will be composed of various wave types of differing characteristics and significance collectively known as seismic waves. These seismic waves will spread radially from the vibration source decaying rapidly as distance increases.Vibration Failure of Young Low-Temperature Concrete Shaft,,The freezing-blasting method constitutes the only available technique for excavating mining shafts within water-bearing bedrock.
