Abstract
The disclosure discloses an automatic simulation test bench and a test method for similar materials of top-coal caving mining. Wherein, the test bench includes a test bench base, a coal seam and strata simulation module, a coal releasing simulation module, a material recovery module, automatic mixing system and a central control system. The disclosure adopts modular construction to meet the requirements of similar material simulation test of top-coal caving mining under different geological conditions and mining technology to the greatest extent. The disclosure adopts automatic control, reduces the working intensity and operation difficulty of the test personnel, and reduces the influence of human factors on the test results. The disclosure adopts a lifting structural design, so as to meet the requirements of similar simulation test of top-coal caving mining under different mining and caving ratios.
