High and steep waste rock slopes are commonly found in open-pit mining,which are areas with severe geolog-ical disasters and vegetation landscape damage,and are also key and difficult points for ecological restoration in mines.At present,the academic scope focuses more on the study of vertical face greening formed by mining,and less attention is paid to the waste rock slopes formed by open-pit mining.There are various greening techniques for high and steep waste rock slopes,but from the perspective of application effects,different technical methods have different applicable conditions and different greening effects.Taking five granite high-steep waste rock slopes in Huanggang City,Hubei Province as the research object,different greening techniques are selected.From the dimensions of slope characteristics,applicable condi-tions,greening effect and later maintenance,the applicable conditions of different ecological greening techniques are dis-cussed with actual cases.The suitability and advantages and disadvantages of various methods are analyzed,and feasible maintenance measures are proposed,providing reference and reference for the selection of similar ecological greening technology methods for slopes in the future.
