Abstract

The invention discloses a simulation test device for visual monitoring of bulk ore and rock migration, which includes a model box, a counterweight and an image recognition device; the model box includes a base and a box with an open top, and the box includes a first The side board, the second side board, the third side board and the fourth side board, the first side board is made of transparent material and the bottom of the first side board is provided with a ore outlet; the box is detachably provided with a partition, A preset interval is maintained between the partition plate and the first side plate; the counterweight is placed at the top opening of the box to exert a preset pressure on the ore particles filled in the box, simulating the discharge under different pressures. Mine test; image recognition equipment is arranged in front of the first side plate to monitor the migration and changes of ore particles during the ore drawing process. The invention can observe the displacement, velocity, stress, deformation and fracture of bulk ore particles in real time during the ore drawing process, thereby overcoming the shortcomings of the traditional ore drawing test device that cannot be observed in real time, visualized and continuously.

Description

technical field [0001] The invention relates to the technical field of analysis of the migration and evolution mechanism of bulk ore and rock in mining engineering, in particular to a simulation test device for visual monitoring of the migration of bulk ore and rock. Background technique [0002] The research on the migration and evolution mechanism of the caving rock is the basis for improving the ore recovery rate and reducing the ore loss and dilution. The size and shape of the ore scattered caving by natural or forced caving are different. The movement form of the particles and the squeezing and collision behavior between the particles during the migration of the ore bulk have a great influence on the ore drawing results. Therefore, exploring the particle displacement, velocity, stress, deformation and fracture during the migration of caving ore plays an important role in improving the recovery rate of ore and reducing loss and dilution. [0003] At present, in order to...
