[0019] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0020] Such as figure 1 As shown, the flow field simulation test device for the goaf of the fully mechanized caving / mining longwall face of the present invention includes a test box 1 filled with a simulated coal seam. The test box 1 is a tempered glass structure with length, width, and height. The simulated coal seam is 3800 mm×2000 mm×1500mm. The simulated coal seam is composed of overlying strata 2 and remaining coal seam 3. The flow field test system of the goaf is provided under the simulated coal seam of the test model box. The system includes a hydraulic lifting device arranged at the bottom of the test box 1, and the hydraulic lifting device includes a plurality of linearly arranged hydraulic lifting rods 5 and a hydraulic device starter 15 interconnected with the hydraulic lifting rods 5. 5 is a pneumatic or oil-driven hydraulic rod.
