Geomechanics 93 - Strata Mechanics/ Numerical Methods/Water Jet Cutting

ABSTRACT

Covers strata mechanics, numerical methods in geomechanics, water jet cutting and mechanical disintegration of rocks. The preface discusses the option of describing typical interdisciplinarity of geosciences, dealing with the processes induced by human activities in geospere, by the word geonics.
