The invention provides a miniature hydraulic support for an analog simulation experiment and a stress test method of the miniature hydraulic support. The miniature hydraulic support mainly comprises a top plate and a base. A guide column is connected between the top plate and the base; an oil cylinder is fixed on the base; the seamless pipe is led out of the oil cylinder and then connected with a pressure measuring hose, and an oil port of the oil cylinder is connected with the other pressure measuring hose; the pressure measuring hose is connected with a liquid inlet and outlet oil pipe of the integrated control multi-channel small mobile hydraulic station; a hydraulic column of the oil cylinder is connected with the top plate; the guide block is connected with the base; the data acquisition system mainly comprises a computer and a data acquisition system. The method realizes the conversion of the hydraulic support from the prototype to the model in the similar material simulation test, is accurate in measur
