explosive charges
Calculation of the shock waves from spherical explosive charges in air
      
Interaction of explosive charges on the surface of a barrier in a hydrodynamic jet model
      
The data have been obtained by using spherical explosive charges.
      
Generation of electric fields by dust grains during the explosions of condensed explosive charges in air
      
Results are presented from two-dimensional numerical simulations of the generation of electric signals during the explosions of chemical explosive charges in air.
      
Blast wave measurements close to explosive charges
      
Size of craters produced by explosive charges on or above the ground surface
      
For explosive charges situated above ground level, the dimensions of the craters are smaller than those observed in underground and near the surface explosions.
      
Laboratory-scale experiments with explosive charges in the milligram range are a useful tool to investigate basic blast wave phenomena and to replicate, to some extent, large-scale explosions.
      
Optical measurement and scaling of blasts from gram-range explosive charges
      
Laboratory-scale experiments with gram-range explosive charges are presented.
      
Piezoelectric pressure gage measurements of overpressure duration at various distances from the explosive charges compare well with theoretical calculations.
      
This procedure allowed to determine maximum acceptable explosive charges.
      
Explosive charges or high-velocity impacts produce high pressures in the kilobar region within microseconds.
      
cooling chambers were used for locating explosive charges in high temperature shotholes.
      
With such rock mass data, the blasting engineer can more readily optimise.a)the diameter, depth and spacing of blastholes,b)the type, quantity and distribution of explosive charges, andc)the lengths of backfill and stemming.
      
The objective was to examine the response of the kerogen rich oil shale to explosive charges in relatively large scale tests.
      
Detonation of two PETN explosive charges on a modified single edge notch (MSEN) specimen provides the dynamic load in the form of a planar tensile wave.
      
A method, based on the measurement of the γ-photopeak at 332 keV arising from a124Sn(n, γ)125mSn reaction, has been developed for the rapid measurement of Sn at concentrations of ~20 μg g-1, present as the cross-linking agent, in explosive charges.
      
explosive charges detonated at depths of 5500m along a 4 km long wide angle reflection profile.
