“…That is implemented by improving the design of the charge using a radial gap between the charge and the wall of the well, which is filled with an inert substance that has high acoustic rigidity. There are studies [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], described above, that offer solutions to a given problem through technological, technical, and organizational measures. However, the common drawback is the impossibility to minimize dust emissions without reducing the effectiveness of rock destruction by explosion.…”

“…The difference of this study from [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] is in that the process of explosive destruction of rocks is managed based on the adapted model by G.M. Lyakhov.…”

“…A dust-gas cloud, which forms during explosive works, pollute the atmosphere not only of quarries and industrial sites, but the residential areas adjacent to them as well [3]. That impacts the health of people living at adjacent areas [4]. Thus, explosions that use 1,000 tons of explosive substances (ES) pollute around 40 million m 3 of atmospheric air that exceeds MPC by tens of times.…”

“…Blasting operations in quarrying sites generate many unfavourable effects on the surrounding areas [1][2][3]. In particular, the most important impact factors resulting from quarrying activities regard phenomena like air blast noise [4], airborne dust [5], gas emissions [6] and ground vibrations [7,8]. Since quarry management have to demonstrate their compliance with legal requirements, in these sites, ground vibration monitoring is, generally, a routine activity.…”

The use of explosives to fragment the rock is very widespread in quarrying activities. This technology produces significant environmental impacts due to ground vibrations generated by blasting operations. In order to characterize this phenomenon, accurate measurements of seismic waves are required and one of the most critical aspects in field tests is represented by the coupling method between the transducers and the soil. This phenomenon may generate the distortion of the recorded waveform thus affecting the affordability of the sample itself. Moreover, the decoupling assumes a growing importance in those sites where the rock is not outcropping and the transducer is buried. For this purpose, different methods are tested in an opencast limestone quarry in the centre of Italy. Firstly, ground vibrations in terms of peak particle velocity (PPV) were recorded according with the method suggested in UNI 9,916 and consisting in burying the detectors into the soil at a suitable depth. Secondly, the same parameters were recorded by means of transducers fixed to the ground with some sand bags thus maintaining the proper adherence. Finally, the data obtained through these two different methods are compared and discussed.
