the driving of explosion , the casing made of the reactive material does not react completely. The velocity of air shock wave produced by the charge with reactive material casing is higher than ...
Revised 13 July 1998 A seismic attenuation and air overpressure study was conducted to determine the attenuation of explosion induced ground motions and air overpressures as a function of distance from ...
the world (Yokoyama 1981). More recently, shock waves were recorded in several explosive eruptions. The 1958 eruption of Mount Asama (Japan) produced terrific detonations and air shocks that were heard ...
A seismic attenuation and air overpressure study was conducted to determine the attenuation of explosion induced ground motions and air overpressures as a function of distance from shallow subsurface ...
equivalents in pressure and impulse vary with the distance nonmonotonically, ranging within 1.4–2.8. The blast wave produced by an infield explosion of a 1.42-kg composite charge demonstrated its high ...
to the blasting source; however, some works have included other physical factors such as an inelastic attenuation factor, a geological factor, or a Burden parameter. The main particle velocity prediction equations ...
spall produced by underground explosions is the relation between the duration of the dwell, which can be predicted from the peak velocity of the uplift, and the depth and yield of the source. The duration ...
of the explosive and Cp is the longitudinal wave velocity in rock. In addition, the Institute of Rock and Soil Mechanics of the Chinese Academy of Sciences calculated the attenuation exponent of the stress wave ...
). (7) 2.2.4 Mechanism of coal rock crack generation under liquid CO2 phase change airburst loading. During coal seam fracturing, a shock wave was produced by a liquid CO2 phase change gas explosion ...
to the elastic zone) to large distances, the static and the dynamic wavefields are affected identically by attenuation and spreading. Hence, the attenuation corrected large distance explosion spectra should ...
