GB/T 23561.8-2009 Methods for determining the physical and mechanical properties of coal and rock—Part 8:Methods for determining the deformation parameters of coal and rock
Abstract
This part of GB/T 23561 specifies the terms and definitions, main instruments and equipment, specimen specifications, pre-test preparations, test procedures, and data calculation involved in the determination of deformation parameters such as the cutting line modulus E50, elastic modulus Et, and Poisson's ratio μ for coal and rocks under uniaxial compression conditions that can be processed into standard specimens under laboratory conditions.
This part is applicable to the determination of deformation parameters such as the cutting line modulus E50, elastic modulus Et, and Poisson's ratio μ for coal and rocks under uniaxial compression conditions that can be processed into standard specimens under laboratory conditions.
