Under subsoil development of mineral deposits there are technologies, where caved enclosing rocks, and rock fill or
broken ore may be within mined-out area (systems with shrinkage, block underground leaching). That is why it is important
to know the peculiarities of rocks deformation properties changing and their influence on stress-strained state of enclosing
massif. Under computer modeling of stress-strained state of rock massif, mathematical models use various characteristics
of rock mechanical properties. In this regard, there are increased requirements to accurately determine the indices, which
characterize these properties. One of the most important deformational characteristics of rocks is the stress-strain
modulus, which characterizes medium contractibility of crushed ore in particular. The purpose of the present work is to
determine the stress-strained modulus of uranium-bearing hard rock of various granulometric composition with the help
of stamp tests. The results of experimental investigations are introduced over the determination of stress-strained
modulus for crushed hard rock of various granulometric compositions, which should be considered when modeling
stress-strained state of rock massif.
Key words: crushed hard rock; granulometric composition; weight-average lump size of crushed hard rock; desk;
deformational properties; stress-strained modulus; stamp.
