Ecological restoration method for high and steep slope of surface mine

The invention discloses an ecological restoration method for a high and steep slope of a surface mine, and relates to the field of ecological restoration, the ecological restoration method comprises the following steps: firstly, treating the slope, removing dangerous rocks and pumice stones of the slope, then hanging a net on the slope, paving an iron wire net on the cleaned slope surface, and fixing the galvanized iron wire net by using ground anchors; then grass bundles are bound, the ecological grass bundles are arranged at intervals from top to bottom according to the slope surface, and after the grass bundles are bound, a second layer of iron gauze is laid again and fixed; finally, carrying out soil dressing spray-seeding, uniformly spray-seeding the mixed planting loam on the slope surface by adopting a hydraulic spray-seeding machine, and then carrying out mixed spray-seeding on grass fibers and grass seeds so as to cover the whole slope surface; according to the remediation method, the high and steep
