高陡废石边坡生态复绿技术方法研究

Study on Ecological Greening Technology of High Steep Waste Rock Slope

高陡废石边坡在露天开采矿山中普遍存在,是地质灾害和植被景观破坏严重的区域,也是矿山生态修复的重难点。目前对矿山开采形成的直立掌子面的复绿研究关注较多,而对矿山开采形成的废石边坡关注较少。高陡废石边坡复绿技术手段丰富,但从应用效果来看,不同的技术手段适用的条件不同,复绿成效也大不相同。以湖北省黄冈地区5处花岗岩高陡废石边坡为研究对象,选取不同复绿技术,从边坡特征、适用条件、复绿效果及后期维护等维度,以实际案例探讨不同生态复绿技术的适用条件,分析各类生态复绿技术方法的适宜性及优缺点,并提出可行性养护措施,为同类型边坡生态复绿技术方法的选择提供借鉴和参考。

High and steep waste rock slopes are commonly found in open-pit mining,which are areas with severe geological 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 conditions,greening effect and later maintenance,the applicable conditions of different ecological greening techniques are discussed 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.
