“…Vibration and air blast generated can create a huge environmental impact, being necessary to control their levels and have a wellestablished procedure, especially with the current trend towards sustainable mining [28,29]. Prediction of both impacts can be very useful in an open pit mine or quarry [30,31] due to the fact their location is usually near to different type of structures, especially in Europe. The main parameters influencing the blast-induced vibration are the geological conditions, properties of blasting work (free faces, decoupling, hole diameter and depth, charge type, and blasting time delay) [18], and explosive material used.…”

A new approach to determine the most efficient blast design was proposed, taking the peak particle velocity (PPV) as the main constraint, while including costs, production, granulometry, air blast and carbon footprint as relevant characteristics. The research was based on a case study that registered and analyzed 548 blasts over more than 10 years, while the vibration of the blast was recorded in 32% of them. A general attenuation law and several local laws were determined based on the geological conditions of the quarry. The blast design improvement allowed one to reduce the specific consumption by almost 30%, 26% of the blast cost in terms of explosive consumption and 18% of the CO2 emissions. This allowed for the achievement of a more environmentally friendly extraction system while complying with the legal standards, the quality requirements and the production and productivity conditions established.

“…The effect of the prospective research is the development of an original and, in particular, effective procedure to record the impact of blasting works with periodical measurements of vibration intensity or monitoring the vibrations' impact on the buildings in the surrounding area [20]. Due to the complex way in which seismic waves propagate near the quarries, the assessment process may show differences between the expected values and those measured during the blasting work.…”

Vibrations caused by blasting works have an impact not only on buildings but also the internal environment of the buildings. If these buildings are situated in the surroundings of quarries, the citizens can perceive these vibrations negatively. By applying an appropriate millisecond timing interval, it is possible to lower the intensity of vibrations to the levels that the citizens will not perceive as negative effects inside the buildings. The limit values for this vibration intensity have not been defined to date. For the protection of the building from the vibrations, normative values of the particle velocity and frequency were determined. Hygienic standards for the inhabitants of the housing were applied, which assessed the impact of the vibration on humans through the measurement of the vibration acceleration in the housing. In this article, the results of the research carried out in Trebejov Quarry are presented. The experimental blasts carried out in Trebejov Quarry proved that the reduction in the vibration intensity under the value 2 mm.s−1 led to the satisfaction of the inhabitants.

“…e soil overburden has a low impact on the ground motion, while the influence of charge weight per delay on the ground wave frequency has diminished [7,8]. Ataei et al found that as the blasting vibration signal is a nonstationary signal, which has the characteristics of short duration and fast mutation, its analysis mainly depends on the signal analysis mathematical methods and the development of corresponding analysis instruments [9][10][11][12].…”

Based on the blasting principle of the cutting seam cartridge, smooth blasting with the charge structures of the usual cartridge and cutting seam cartridge has been designed and implemented, respectively, for different peripheral holes in the same face. Meanwhile, the blasting vibration has been monitored. Through the analysis of the frequency spectrum of blasting vibration signals, it is found that the maximum blasting vibration velocity of the cutting seam cartridge charge is lower than that of the usual cartridge charge, from 0.21 m/s to 0.12 m/s. Moreover, the blasting energy distribution is more balanced. Especially in the low-frequency part, the blasting energy is less, and there is a transferring trend to the high-frequency part, which shows that the cutting seam cartridge charge has a better optimization effect. Furthermore, using wavelet packet analysis, the cutting seam cartridge charge could effectively reduce the energy concentration in the low-frequency part. The energy distribution is much more dispersed, and the disturbance to the structure could be less, which is conducive to the stability of the structure. According to the blasting effect, the overbreak and underexcavation quantity at the cutting seam cartridge charge is better than that at the usual cartridge charge.
