Therefore, when the slope is steep during mining, it is necessary to reinforce the slope to reduce the probability of natural risks.

[0004] In the prior art, a mine landslide prevention reinforcement structure disclosed in Chinese utility model patent CN209555949U includes a retaining wall and a fixed drill inserted into a mine, wherein the fixed drill has multiple pieces and is arranged perpendicular to the slope and / or the ground. The fixed drill includes a drill rod and a supporting plate and a supporting member arranged inside the drill rod, wherein a first through hole is arranged on the circumference of the drill rod, and four supporting plates are symmetrically arranged. A hollow reinforcing pipe nail is arranged on the outer side of each supporting plate, and the position of the hollow reinforcing pipe nail is arranged corresponding to the first through hole. The cross section of the supporting member is a cross-shaped structure, and a third through hole is provided on the surface of the supporting member; the retaining wall is arranged at the foot of the slope, the connecting slope of the retaining wall is arranged with the ground, and the retaining wall wraps the upper end of the drill rod to expose the mountain part, and the interior of the fixed drill is filled with concrete.
