Abstract: The invention discloses an experimental device for natural gas hydrate solid-state fluidized mining and crushing, the experimental device comprising a power liquid supply module, a hydrate suction module, a pipeline conveying module, a hydrate fluidized crushing module, a secondary processing module and an experimental data information collection and processing module. An experimental method for the experimental device comprises: turning on the power liquid supply module, the hydrate suction module, the pipeline conveying module, the hydrate fluidized crushing module and the secondary processing module, and collecting pressure and flow data at a plurality of locations by the experimental data information collection and processing module. The present invention has the following beneficial effects: a jet solid-state fluidized mining process is simulated, and a plurality of pressure and flow detection points and sampling ports for crushed samples are provided at the same time so as to facilitate parameter collection; a plurality of component parameters are flexibly variable, including changing a drag-back speed of a moving slider, shape parameters of jet nozzles, and a pressure and flow of a power liquid; a spray head is designed to simplify the experimental device, and a dynamic process of jet crushing may be observed from a side surface of an experimental tank.
