Abstract
The article describes some aspects of the research and applied works, which the authors carried out to expand the scope of application in the study of rock strength indicators in the laboratory of KuzSTU (Prokopyevsk branch) on a complex equipment. It consists of an extreme deformation chamber and a volumetric compression chamber. It describes the disadvantages of the volumetric compression chamber. The disadvantages have been eliminated by using a special device for fixing the sample when descending into the volumetric compression chamber. The article also gives the description of the operation of a volumetric compression chamber with the possibility of testing rock samples for a breakage under the volumetric compression. The first test results are presented.

Summary
The paper [1] outlines the need to expand the strength indicators of rocks. It is necessary since at present, there is a need for active use of such indicators as adhesion C and the angle of internal friction φ in addition to the characteristics of uniaxial tension of the compression. For these purposes, at KuzSTU (a branch in Prokopyevsk) the authors actively use the Azimuth 85 D01 volumetric compression chamber, and in combination with the BV-21 an excessive deformation chamber. The article is devoted to some aspects of the research and applied works carried out by the authors
