Abstract

The complete diagrams of rocks compression with deformation above compressive strength are considered. Strength properties of rocks at the volume compression are defined: compressive strength, residual strength, modulus of deformation above com-pressive strength. Physical relationships are used: failure criteri-on, the energy equation of the limit beyond deformation, and experimental laws. The theoretical values of the maximum rock strength comply with the experimental data. It is proposed to use the results for the forecast of rock pressure and the safety of mining. It is identified that the modulus of deformation above compressive strength equals modulus of deformation before reaching this limit.
