GB/T 23561.8-2024 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 document specifies the main instruments and equipment, specimen specifications, pre-test preparations, test procedures, and data calculation methods for determining the deformation parameters of coal and rocks, including the secant modulus (E50), elastic modulus (Et), and Poisson's ratio (μ) under uniaxial compression conditions where the samples can be processed into standard specimens under laboratory conditions.
