“…The implementation of gob-side entry retaining (GER) technology provides technical support for the successful execution of deep continuous pressure relief mining and deep coal and gas mining. It achieves this by reducing the necessity for extensive roadway excavation, mitigating mining tension, enhancing resource recovery efficiency, eliminating stress concentration on coal pillars, and addressing the issue of gas accumulation in upper corners [ [1] , [2] , [3] , [4] , [5] , [6] ]. Over time, GER technology has been progressively applied across various coal seam thicknesses - from thin seams (less than 1.3 m) [ [7] , [8] , [9] ], medium-thick seams (1.3 m–3.5 m) [ [10] , [11] , [12] ], fully mechanized thick seams (more than 3.5 m) [ [13] , [14] , [15] ], to even fully mechanized top coal caving mining operations [ 16 , 17 ].…”
