[0028] The bottom plate 110 is placed on the ground of the mine passage, and the height of the horizontal plate 210 and the supporting plate 220 above the horizontal plate 210 are gradually adjusted by the lifting rod part 130 until the multiple supporting plates 220 above the horizontal plate 210 are in contact with the top wall of the passage. Due to the elastic support of the elastic support part 230, the multiple supporting plates 220 above the horizontal plate 210 can be supported respectively according to the distance between them and the top wall of the passage. Compared with the traditional single-point adjustment support method, the support combined device has comprehensive support point coverage and the support adjustment is faster and more convenient.

[0029] In the above specific implementation, please refer to Figure 3 The lifting rod 130 includes a sleeve 131 and a first threaded rod 132.
