Propagation of Ground Vibration: a Review
An important environmental aspect of building and facility design is the evaluation of vibration transmitted to the site, through the ground, from external sources. Such external sources may include highway traffic, surface and subsurface railways, and machinery in nearby locations. To properly predict excitation levels at a building due to such sources, one must be able to predict how much vib...
متن کاملNumerical Analysis of the Primer Location Effect on Ground Vibration Caused by Blasting
Ground vibration is one of the undesirable results of blasting operations. Different methods have been proposed to predict and control ground vibration that is caused by blasting. These methods can be classified as laboratory studies, fieldwork and numerical modeling. Among these methods, numerical modeling is the one which saves time and cuts costs since it takes into account the basic princip...

متن کاملBreakage and fragmentation modelling for underground production blasting applications
A review of breakage and fragmentation modelling literature has shown that only a few methodologies have been specifically developed for applications in underground production blasting. These approaches however, have applied empirical relations that do not adequately consider ring blasting geometries; have failed to appropriately respond to changes in basic design input parameters; and have pro...
متن کاملVibration Control of Underwater Blasting Works using Artificial Neural Networks
To allow the access of larger ships (Panamax class) to the interior docks of an important harbour in Portugal, a large volume of submerged rock had to be blasted. The harbour is surrounded by a densely populated urban area and the authors of this work were hired to monitor vibrations caused by the blasts. Macro-seismometers were installed in several locations inside the harbour perimeter and in...
