“…Furthermore, the potential damage of blast-induced vibrations on structures is conditioned by the particle velocity and the low-frequency portion of seismic waves. The lowof sites are determined by monitoring the ground vibrations at variable distances for identifying the blasting parameters [12][13][14][15][16]. The PPV is related to the charge weight and distance by the prediction equation (1) proposed by the USBM:…”

“…1, empirical technique was widely used for predicting blast-induced PPV in open-pit mine [5,39]. Many scholars have proposed and developed empirical equations for predicting blast-induced PPV [8][9][10][11][12][13][14][15][16][17][18]. Review of the literature showed that the United States Bureau of Mines (USBM) empirical equation was widely applied for estimating blast-induced PPV which was proposed by Duvall and Petkof [8].…”

“…To assess and predict blast-induced PPV, many scientists have access to empirical techniques based on mathematical statistics [8][9][10][11][12][13][14][15][16][17][18]. Empirical techniques were mostly based on mathematical statistical methods and used two input variables including explosive charge per delay/maximum explosive charge capacity (W) and monitoring distance (R).…”

Blasting is one of the cheapest and effective methods for breaking rock mass in open-pit mines. However, its side effects are not small such as ground vibration (PPV), air overpressure, fly rock, back break, dust, and toxic. Of these side effects, blast-induced PPV is the most dangerous for the human and surrounding environment. Therefore, evaluating and accurately forecasting blast-induced PPV is one of the most challenging issues facing open-pit mines today. In this paper, a series of artificial neural network models were applied to predict blast-induced PPV in an open-pit coal mine of Vietnam; 68 blasting events were used in this study for development of the ANN models. Of the whole dataset, 80% (approximately 56 observations) were used for the training process, and the rest of 20% (12 observations) were used for the testing process. Five ANN models were developed in this study with the difference in the number of hidden layers.

“…e in uence of rock mass joints on the attenuation law of the blasting vibration should be considered comprehensively to predict the exact PPV of blasting, and thus the attenuation equation needs to be modi ed. According to the studies conducted by Simangunsong and Wahyudi [32], the in uence of the number of coal seams should be considered in the prediction of blasting vibration. e proposed modi ed equation for PPV and SD can be expressed as follows:…”

In an open-pit mine slope, rock mass has multiple joint structures and blasting operations have an obvious influence on its stability. Therefore, accurately predicting the blasting vibration is necessary to ensure slope stability. In this study, the blasting vibration signals monitored at a blasting site with different rock masses were used to investigate the attenuation characteristics of blasting vibration through the peak particle velocity (PPV), frequency characteristics, and energy distribution of the blasting vibration signals analyzed with the time-frequency processing method. The results demonstrated that the main vibration frequency of the blasting vibration of dolomite was wider than that of shale, and these main vibration frequencies occurred at 25 kHz and 14 kHz for dolomite and shale, respectively, at a distance of 50 m from the blast area to the vibration monitoring point. With an increase in the distance from 50 m to 200 m, the main vibration frequencies decreased to less than 5 Hz. With increasing joint degree, the attenuation rate of the vibration velocity and energy attenuation of the blasting vibration increase, indicating that the structural parameters of the rock mass (such as the number of joints) have a significant impact on the attenuation law of blasting vibration. Furthermore, a modified equation that can be used for predicting PPV was developed by considering the effect of the number of joints in the rock mass on the blasting vibration. For the same ground vibration readings, the correlation factor increased from 0.8 to 0.85 for the Nicholls-USBM equation and the modified equation, respectively. The PPV of blasting under different rock masses of the Baideng open-pit phosphorite mine was used to verify the modified equation. The results show that a modified equation can be used for predicting the PPV of blasting engineering in the Baideng phosphorite mine and that the prediction accuracy is acceptable.
