Provided is an experimental apparatus for simulating lifting operation of deep-sea mining, which relates to the technical field of experimental equipment of deep-sea mining. By this apparatus, dynamic characteristics of a spatial structure when simulating lifting operation of deep-sea mining are solved. The apparatus includes an experimental box, a wave-making mechanism, a flowrate control mechanism, a mining simulation mechanism and a monitoring mechanism. The wave-making mechanism includes a control box and a wave-pushing board for simulating waves. The flowrate control mechanism includes a water pump, a motor, a grating board and a manifold so that the flowrate and the flow volume can be adjusted by the grating board and the manifold. The mining simulation mechanism includes an experimental ship model, a lifting pipe, a material-mixing pipe, a mineral slurry pipe, a material-delivering pipe and a material-returning pipe for simulating lifting operation states. The monitoring mechanism includes a wave height measurer, a displacement sensor, a flowrate measurer and an image collection apparatus for detecting dynamic influence of the wave height and the wave speed on the mining simulation mechanism during a mining process, especially during lifting operation. Further, the apparatus has advantages such as multi-parameter real-time monitoring, low fabrication cost and simple operation.
