Upstream method in-service tailing pond fill dam slope soilless greening structure

The utility model discloses an upstream method in-service tailing pond fill dam slope soilless greening structure. Vegetation bags with separation cavities are arranged on a fill dam slope in an attached mode. Edges of a bag body surface layer and a bag body bottom layer of the vegetation bag with the separation cavity are connected with each other to form a hollow-structure bag body, a separation layer is arranged in the bag body, the edge of the separation layer is connected with the edge of the bag body, a seed germination cavity filled with a seed germination base material is formed between the bag body surface layer and the separation layer, and a vegetation growth cavity filled with a vegetation growth base material is formed between the bag body bottom layer and the separation layer. The bag body bottom layer is tightly attached to the earth-facing side of the fill dam slope, and the bag body surface layer faces the free side. The plant-growing bags with the separation cavities are arranged on the slop
