Characteristics and Energy Distribution of Blast-Induced Ground Vibration in Deep-Hole Blasting

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 velocity surface when value increases. Finally, relation plane increasing extremum position several sets measured studied. Based statistical analysis, results show that vertical direction has a significant advantage over other two directions, primarily distributed range 60°~90°. After unstable velocities transition zone, each gradually attain relatively balanced stable attenuation condition as distance proves reliability analysis understanding mechanism rock
