大气降雨入渗-采空区产汇流相似材料模拟试验装置
By designing a simulated experimental device for atmospheric rainfall infiltration and goaf runoff generation, the hydrogeological structure of the goaf was visualized and monitored. This solved the correlation problem between atmospheric rainfall infiltration and goaf runoff generation, and provided theoretical support for safe mining and water hazard early warning.

AI Technical Summary
Existing technologies have failed to effectively establish the correlation between atmospheric precipitation infiltration and runoff generation in goaf areas, and lack similar simulation test platforms, resulting in insufficient support for early warning of water hazards and safe production in coal mines.
Design a simulated experimental device for atmospheric rainfall infiltration-mining goaf generation and confluence similar materials, including a transparent model box, a multi-layer rock layer module, a fracture zone simulation device, a rainfall control system, a fracture water pressure sensor and a flow meter, to realize the visualization of the experimental process and real-time data monitoring.
This study revealed the evolution characteristics of runoff generation and confluence paths in goaf areas under different rainfall intensities, clarified the quantitative correlation between infiltration rate and water accumulation rate, provided a theoretical basis for early warning of rainfall-induced water hazards in deep coal seam re-mining areas, and optimized safe mining and hydrological ecological protection in mining areas.
