煤和岩石物理力学性质测定方法 第9部分：煤和岩石三轴强度及变形参数测定方法
Application Summary AI generated
This standard specifies the test procedures for measuring the triaxial compressive strength and deformation parameters (such as elastic modulus and Poisson's ratio) of coal and rock samples under confining pressure. It is applied in the mining industry for evaluating the mechanical behavior of geological materials under in-situ stress conditions, particularly for designing underground excavations, supporting structures, and assessing rockburst risks in coal mines.
