Application Summary AI generated

This standard specifies the test methods for determining deformation parameters such as elastic modulus and Poisson's ratio of coal and rock samples under uniaxial or triaxial compression. It is applied in the mining and geotechnical engineering industries for evaluating the mechanical behavior of coal and rock masses, particularly in the context of mine design, stability analysis, and underground excavation safety.
