Abstract: Ecological restoration of rocky high and steep slopes is a difficult technical project.The slopes are high and steep,and the rock mass is hard,and it is difficult to ecologically repair them with common greening techniques.This article takes the practice of mine geological environment treatment engineering in the suburbs of Tongshan City and the newlybuilt Baiyangluo Stone Material Plant as examples to introduce in detail the structural design of the planting trough,the greening design in the trough,the matrix ratio,and the maintenance system.Existing problems are elaborated.Through the implementation of this project,it provides a certain reference for the ecological restoration of other rocky high and steep slopes in Tongling City.

Key words: Rocky slope, Ecological restoration, Planting trough, Slope green
