[0037] The present invention will be further described below in conjunction with the accompanying drawings.
[0038] like Figure 1 to Figure 4 As shown in the figure, a large mining height gob-side entry retaining roadway filling structure includes a single hydraulic prop 5, a steel mesh 6 and a filling bag 1;
[0039] The plurality of single hydraulic struts 5 are divided into two rows, and are respectively vertically supported on the outer sides of both ends of the width direction of the area to be filled;
[0040] A plurality of reinforcement meshes 6 are sequentially arranged around the area to be filled, and are hung on the inner side of the single hydraulic support 5, and a three-dimensional filling space of the wall to be filled is enclosed above the area to be filled;
[0041] The filling bag 1 is a three-dimensional structure with a closed space, and its height is the same as the distance between the bottom plate 14 and the top plate 13 in the area to be filled; Ab...
