Blaspa
includes simulators which make it possible to evaluate
the intensity of the blast induced vibrations for a
given blast method in a given rock. A simulation
calculates the particle velocity U in mm/sec at
distance D from the explosion of the column of
explosives.
There is one
simulator < VibMas > which deals with the vibrations
caused by the movement of the rock mass resulting
from the blast, and another simulator < VibShock >
which deals with the vibrations caused by the passage
of the shock wave.

Vibrations caused by the movement of the rock
mass

The simulator <
VibMas > calculates the particle velocity of the rock
U at a given distance D from the blast hole, caused by
the movement of the rock mass resulting from the
blast; this type of vibration of the rock is that
which usually causes the major perturbation at large
distance from the hole. The user can obtain the value
of the particle velocity of the vibration either at
the distance D which he specifies, or alternately he
can specify the value of the particle velocity which
is important to him and then the simulator informs him
of the distance at which the blast will cause that
level of particle velocity. For more information

Another simulator <
VibShock > calculates the particle velocity of the
rock at a given distance D from the blast hole, caused
by the passage of the shock wave; this type of
vibration of the rock is that which usually causes the
major perturbation at short distance from the hole.
