Abstract：A large model test system for deep mine construction was developed at China University of Mining and Technology(Beijing)，which is mainly composed of supporting frames，a system of hydraulic loading，a system of measurement and control and a system of data acquisition. The supporting frames have a main frame，a movable door shaped supporting frame at front and a support frame at rear. The thickness of models can be adjusted for 2D model test and 3D model test. The hydraulic loading system including vertical actuators(up and down)，horizontal actuators(right and left) and rear actuators，achieves loading in five directions. A constant load maintaining system is set on the equipment. The measurement and control system can accurately control the loading in real-time with a closed loop digital control system composed of a PC，a EDC220 digital controller，sensing elements and executing components. The system of data acquisition including the static and dynamic strain gauges collects the information during the simulation test on roadway construction by mechanical or blasting methods. A model test was carried out with the model test system to simulate the failure and fracture phenomena of the roadway made of gypsum block material.
