Experimental device and experimental method for simulating form of caved body of deep caved ore

The invention discloses an experimental device and an experimental method for simulating the form of a deep caved ore caving body, and belongs to the technical field of ore mining. The experimental device is composed of a model framework, an ore drawing system and a pressure applying system, and the ore drawing system and the pressure applying system are arranged on the model framework; the experimental method comprises the steps of obtaining ore particles for experiments, filling the ore particles, applying pressure, recording the amount and analyzing. According to the invention, the caved ore caved body form under the deep high overburden pressure effect can be simulated; in addition, end ore drawing body form measurement and bottom ore drawing body form measurement under deep high overburden pressure can be achieved on one set of equipment, and the application range is wider; the method can be used for measuring the flow characteristic of caved ore bulk and the form of a caved ore caved body under the acti
