Fully mechanized coal mining face mine dust simulation experiment device and mine dust simulation experiment method

The invention provides a mine dust simulation experiment device and method for a fully mechanized coal mining face, and the device comprises a protection housing which is internally provided with a testing cavity; the protective shell is further provided with a first circulation opening and a second circulation opening. The first fan is arranged at the first circulation opening, and the second fan is arranged at the second circulation opening; the coal mining simulation assembly is movably arranged in the test cavity and comprises a rotatable roller; the coal mining dust generator is arranged on the coal mining simulation assembly; the coal mining dust generator sprays dust to the rotating roller; a measuring assembly; wherein the first fan and the second fan are matched to work to generate air flow to drive dust to directionally move along the test cavity so as to simulate the state of the mine dust on the fully mechanized coal mining face in the roadway. According to the invention, the dust diffusion rule o
