A technique for constructing the curves of dynamic compressibility 
of powder media from the results of an experiment on a plant of hydraulic 
explosive pressing is suggested which makes it possible to construct 
a certain portion of the compressibility curve with the aid of one 
experimental shot for any powder material in the pressure-density 
coordinates to the total exclusion of the apparatus that could register 
the dynamic parameters of the process of pressing. The technique is 
used for predicting the results of pressing concrete articles from 
powder materials, in particular, to determine the parameters of a 
charge and the coordinates of its disposition in a transmitting liquid 
medium to obtain a blank with prescribed properties.
