The invention relates to a coal-rock sample real triaxial vertical dynamic-static loading tester, which is applicable to reappeared impact mineral pressure, rock explosion and other coal-rock power disasters during a underground mine mining process. The testing system is composed of a triaxial loading system, a measurement control system, and a power loading system; X and Y axes are provided with double high-frequency response servo cylinders of four-pillar and two-pillar single piston cylinders, and installed on the same one horizontal platform driven by a lifting servo mechanism along the Z axis direction, wherein one direction of the Y axis is provided with an unloading cylinder to realize the rapid unloading of stress at one face; the Z axis is provided with a four-pillar hollow type dual-piston rod single servo cylinder, and configured with a resilience type displacement sensor, the measurement data feeds back to the lifting servo mechanism, and guarantees that the loading center of the horizontal X and U axes is always intersected at one point and the center point is unchanged. The high-speed servo cylinder is installed on the Z axis for providing the power source. The tester can simulate the real triaxial vertical dynamic-static loading state of the coal-rock sample, the Z-axis impact power loading state, the Y-axis fixing rate or rapid stress unloading state.
