Ecological Restoration Techniques for Steep Slopes in Limestone Mines
The poor site conditions and difficult ecological restoration of high and steep slopes in limestone mines have always been a problem that troubles the industry.Through field investigations of numerous domestic engineering cases and analysis of ecological restoration effectiveness,13 effective ecological restoration techniques have been proposed,including slope cutting and storage restoration,step shaped shaping restoration,concrete lattice soil stabilization restoration,ecological bag restoration,high-order particle hanging net spraying restoration,fish scale pit restoration,vegetation hole restoration,vegetation basin restoration,vegetation trough restoration,micro terrain cofferdam restoration,guest soil spraying restoration,tree shading restoration,and vine vegetation shading restoration.This article summarizes these technical methods and summarizes the applicable conditions,in order to provide reference for ecological restoration of high and steep slopes in limestone mines.
