Device and method for simulating collapse of mining rock bodies in iron ore outdoor well transformation

The invention relates to a device and a method for simulating collapse of mining rock bodies in iron ore outdoor well transformation. The device includes a movable model box, an ore body simulation box and a transmission system. The method includes the steps of: determining geological conditions, hydrology geological conditions, geological construction, stratum lithology of a mining area and a deep part ore body exploitation process; determining an installation position of a first side face of the movable model box according to an experiment dimension, determining the size of the ore body simulation box and a stacking layer number of the box body according to a model similitude ratio, and determining parameters of an ore body simulation material; employing a similarity theory according to the on-site deep part ore body exploitation process, extracting the box bodies of the ore body simulation box at a rectangular hole of a lower end of the first side face of the movable model box one by one through the transm
