Impact of orientation of blast initiation on ground vibrations
Journal of Rock Mechanics and Geotechnical Engineering, 2023 The blast-induced ground vibrations can be significantly controlled by varying the location and orientation of point of interest from blast site. The blast waves generated due to individual holes get superimposed and resultant peak particle velocity (PPV)

Investigation and Control of the Blasting‐Induced Ground Vibration under Cold Condition [PDF]
Shock and Vibration, 2021 This paper focuses on the investigation and control of the blasting‐induced ground vibration under cold condition. The mechanical performance and wave propagation characteristics of the frozen rock mass are quite different from that of the conventional condition.

Study on blast-induced ground vibration velocity limits for slope rock masses
Frontiers in Earth Science, 2023 Seismic waves induced by blasting can cause damage to slope rock masses and thus lower the stability of the slope. The vibration standards of many countries do not specify the allowable blasting vibration velocity for slope rock masses.

Application of Bayesian Neural Network (BNN) for the Prediction of Blast-Induced Ground Vibration
Applied Sciences, 2023 Rock blasting is one of the most common and cost-effective excavation techniques. However, rock blasting has various negative environmental effects, such as air overpressure, fly rock, and ground vibration. Ground vibration is the most hazardous of these

Journal of Rock Mechanics and Geotechnical Engineering, 2023 Surface ground motion produced by underground blasts is significantly influenced by near-surface geological conditions. However, near-surface low-propagation velocity layers were always ignored in past analyses of ground motions due to their thin ...

Frequency control of blast-induced ground vibrations. [PDF]
The Journal of the Acoustical Society of America, 1991 A site-specific approach is presented for controlling the amplitude, frequency, and duration of ground vibrations induced by blasting operations. Using measured single-charge response functions, and proper frequency control of the pulse train excitation applied to the overburden, significant reductions in vibration amplitude and duration may be ...

Evaluation of parameters affected on the blast induced ground vibration (BIGV) by using relation diagram method (RDM) [PDF]
Acta Montanistica Slovaca, 2010 This paper presents the application of relation diagram method (RDM) to determine contribution of the parameters affectedon the blast induced ground vibration. There are two types of parameters: controllable and uncontrollable parameters.
