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.

Examines the structural evolution of the Earth's crust from the Triassic period to the present. The book describes the patterns of distribution, and the composition and accumulation conditions of formations in the various geological periods in all the continents and oceans.

Translated from Russian, this text looks at the development of the earth's crust in the Palaeozoic period and starts from the Vendian to the Late Cambrian period. Moving on to include Ordovician to the mature stage of Caledonian and initial stage of development of Hercynian mobile belts; Silurian-Early Devonian. The completion of development of the Caledonian and early, mature and end stages of the Hercynian mobile belts; the birth of Cimmerian mobile belts and ending with the Palaeozoic.
The book considers the propagation of shock and continuous waves in solid plastic media, wave refraction on media interfaces, and also interaction with the elements of structures. The problem of considering viscous properties of media when solving certain wave problems is considered. The results are applied also to waves in rods. Specific attention is given to the presentation of laboratory findings on the dynamic properties of soils and on the regularities of the propagation of pressure waves in soils. Information from the general theory of shock waves, which is necessary for understanding the basic material, is presented. (Author).
Discussing rock breakage by blasting, this text includes: results of complex investigations into the rock breakage mechanism and the patterns of crack formation during a blast; problems of modelling; and principal equations linking the model with prototype and similarity criteria.
