This study proposes an incremental extreme extraction method based on the waveform characteristics of ground vibration signals obtained from open-pit mines to investigate distribution and deep-hole blasting. Firstly, is proposed borehole blasting in mines. The could extract screen values effectively improve utilization rate data. space vector particle introduced analyze angle change between vel...

In recent decades, the effects of blast loads on existing structures have gained considerable attention due to increase in threat from various activities. Site-specific empirical relationships for calculation blast-induced vibration parameters like Peak Particle Velocity (PPV), Acceleration (PPA), and Displacement (PPD) are commonly used estimation impact blasting an adjacent tunnel. However, th...

Ground vibration induced by rock blasting is an unavoidable effect that may generate severe damages to structures and living communities. Peak particle velocity (PPV) the key predictor for ground vibration. This study aims develop a model predict PPV in opencast mines. Two machine-learning techniques, including multivariate adaptive regression splines (MARS) classification tree (CART), which ar...

The paper defines and describes blast waves, their interaction with a structure and its subsequent response. Explosions generate blast waves, which need not be due to explosives. A blast wave consists of two parts: a shock wave and a blast wind. The paper explains how shock waves are formed and their basic properties. The physics of blast waves is non-linear and therefore non-intuitive. To unde...
