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 industry for evaluating the mechanical behavior of geological materials during underground excavation, support design, and stability analysis of coal seams and surrounding rock.
