The triaxial loading test device for coal and rock is experimental equipment used to study the mechanical properties of coal and rock. It is mainly used to simulate the mechanical behavior and failure laws of coal and rock under complex stress conditions. This device is widely used in coal mining, oil and gas mining, and geological hazard prevention and control.
