Abstract
A tempo-spatial evolution test system for rock breaking in deep and complex environment includes an acoustic emission sensor assembly and an acoustic emission amplifier assembly that are arranged on a rock mechanics test system. A triaxial cavity coupling bracket is arranged on an outer wall of the triaxial cavity and between two sets of acoustic emission sensor assemblies. The triaxial cavity coupling bracket includes a plate-shaped bracket, two sickle-shaped brackets, and at least three bracket bolts, which can be tightly wrapped on the outer wall of the triaxial cavity. A lateral side of the plate-shaped bracket vertically fixes two guide columns. The acoustic emission amplifier assembly is arranged between the two guide columns and is located above the plate-shaped bracket, and the acoustic emission amplifier assembly is connected to the acoustic emission sensor assembly through a signal line.
