ajst-30173	Lv, Xiaodong	Study on Similarity Simulation Test of Overburden Movement Law in Fully Mechanized Mining Face	2025	3	.pdf	application/pdf	2390	114	52	Mining surface pressure law The experiment utilizes strain gauges to record the deformation on the simulated hydraulic supports, which is then converted into load values. At this stage, the slump height reaches 13.75 m, and the height of the separation layer is 16.25 m. This marks the first occurrence of roof pressure, with the initial pressure step observed at 50 m of advancement, as illustrated in Fig.2.	cache/ajst-30173.pdf	txt/ajst-30173.txt
