Surface Subsidence Characteristics Research Using a Three-Dimensional Test Device to Simulate Rock Strata and Surface Movement
Author(s): Hazel Scarlett*
The primary functions of a three-dimensional test system for mimicking rock formations and surface movement caused by underground coal mining were detailed, and a series of associated tests were performed. An outside frame, a pressurization unit, a pulling unit, and a coal seam simulation component comprised the device. A model test research on the surface subsidence features produced by coal seam mining was carried out using this test apparatus, which was backed by monitoring methods such as the three-dimensional laser scanning method. The transfer law of surface subsidence produced by coal seam mining was discovered when combined with field measurements, and the entire surface subsidence reaction process was investigated. According to the experimental data, subsidence produced by mining disturbances below the coal seam accounts for 79.3 percent of overall subsidence, making it the d.. View More»
