Excessive blast-induced vibration may cause damage and even the collapse of
underground tunnels, and the monitoring and prediction of vibration have an important …

The method of cut blasting is widely used in tunnelling excavation, which concerns the
success in subsequent stop blasting and smooth blasting. Rock masses in deep tunnels are …

A microspheres-sensitized emulsion explosive, to be used in rock blasting tests, is
characterized by means of the cylinder test. This test measures the expansion of a copper …

A model for fragmentation in bench blasting is developed from dimensional analysis
adapted from asteroid collision theory, to which two factors have been added: one …

Ammonium nitrate and fuel oil (ANFO) based explosive is a classic example of non-ideal
high explosives. Its detonation is characterized by a strong dependence of detonation …

Borehole blasting is a technique widely applied to form fracture networks in coal masses.
There are many original cracks in coal masses, such as bedding planes and cleat planes …

Terrorist attacks or contact explosions could trigger severe damage to structural components
or even cause the local or global collapse of the structure in civil engineering and …

It is shown that blast fragmentation data in the form of sets of percentile fragment sizes, x P,
as function of specific charge (powder factor, q) often form a set of straight lines in a log (x P) …

In rock blasting, the blast of the former delay always creates new free surfaces for the latter.
And the blast-generated free surfaces play a critical role in blasting vibration. A quantitative …

During blasting in deep mining and excavation, the rock masses usually suffer from high in
situ stress. The initial seismic energy generated in deep rock blasting and its attenuation …
