Zusammenfassung:	The utility model relates to a mining arc-shaped anti-impact sealing wall. Prior to the manufacture of the mining arc-shaped anti-impact sealing wall, first channels are dug at the positions of a roadway needing to be sealed. The channels are continuously distributed along a left laneway side, a right laneway side, a top plate and a base plate. The channeling depths are 500 mm, and the widths are 500-800 mm. According to the coming direction of air waves, the mining arc-shaped anti-impact sealing wall sequentially comprises a flow guide layer, a filling layer, an arc-shaped steel plate layer, a concrete sealing wall and a plane steel plate layer from inside to outside, wherein each layer reaches the channeling edges of the left laneway side, the right laneway side, the top plate and the base plate.
