[0025] like Figures 1-6As shown, the adjustable support for mining construction provided in this embodiment includes a base 1. There are two bases 1, symmetrically distributed. A sliding rod 2 is slidably connected to the inner wall of the base 1. The front of the sliding rod 2 is inlaid with equally spaced internally threaded tubes 3. A positioning hole 4 is provided on the front of the base 1, and a positioning bolt 5 is provided on the positioning hole 4. One end of the positioning bolt 5 is threadedly connected to the internally threaded tube 3. A weight-reducing groove 6 is provided on the side of the base 1. An ear plate 7 is fixedly connected to the front of the bottom of the base 1. A through hole 8 is opened on the upper surface of the ear plate 7. Anchor bolts 9 are installed in the through hole 8. When installing the bracket, adjust the length of the sliding rod 2 inside the base 1 to adjust the combined length of the base 1 and the sliding rod 2, so as to match the height of the roadway. Then, pass one end of the positioning bolt 5 through the positioning hole 4 and tighten the positioning bolt 5 in the internal threaded tube 3 to fix the base 1 and the sliding rod 2 together. The position of the sliding rod 2 inside the base 1 can be observed at the weight reduction groove 6. After the base 1 is erected, the anchor bolts 9 are passed through the through hole 8 and fixed to the roadway floor to fix the base 1.

[0026] In this embodiment, as Figures 1-6 As shown, a fixing hole 10 is provided on the side of the sliding rod 2. A pin 11 is provided inside the fixing hole 10. The pin 11 is passed through the fixing hole 10 and fixed to the side wall of the tunnel, thereby fixing the sliding rod 2 to the side wall of the tunnel. A slot 12 is provided on the upper surface of the sliding rod 2. A connecting hole 13 is provided on the top side of the sliding rod 2. The interior of the connecting hole 13 communicates with the slot 12. A support rib 14 is provided on the top of the sliding rod 2. The support rib 14 is arc-shaped. An insert 15 is fixedly connected to the lower surface of the support rib 14. A screw hole 16 is provided on the side of the insert rib 15.
