Description and Table of Contents
Description
This work provides a translation of "Modelirovanie deistviya vzriva pri razruzhenii gornikh porod" (Moscow, 1990). Presenting theories of simulating blast effects in elastic and elastoplastic media, it covers topics such as the classical and modern methods for modelling rock breakage by blasting.
