The invention discloses a test system for failure spatiotemporal evolution of rock in a deep complex environment. The system comprises an acoustic emission sensor assembly and an acoustic emission amplifier assembly which are arranged on a rock mechanical test machine, wherein a three-axis cavity coupling bracket is arranged on the outer wall of a three-axis cavity and between the two acoustic emission sensor assemblies; the three-axis cavity coupling bracket comprises a plate-shaped bracket, two sickle-type brackets and at least three bracket bolts which can be tightly hooped on the outer wall of the three-axis cavity; two guiding columns are vertically fixed on two side faces of the plate-shaped bracket; the acoustic emission amplifier assembly is arranged between the two guiding columnsand above the plate-shaped bracket; and the acoustic emission amplifier assembly is connected to the acoustic emission sensor assembly through a signal line. Through the test system disclosed by theinvention, the problems of
