Research on slope ecological restoration and management in mining areas on loess plateau：planting support technology of PVC plates lattice anchor beam

In order to protect ecological environment of loess plateau mining area and solve problem that traditional engineering measures have poor landscape effect and structure is prone to failure over time， slope ecological restoration and management by using vegetation for slope protection and erosion control can realize long-term effective function of soil retaining and slope protection and environmental protection.In view of current of loess plateau mining areas of slope ecological recovery vegetation planting support structures with large weight，and late strength damage defects problem， based on PVC plates with acid and alkali resistance， salt resistance， rich raw materials， low quality， no harm， better durability， friendly to environment and features of comprehensive advantages of transportation cost， construction period and later maintenance， this paper proposes vegetation planting support technology of PVC plates lattice anchor beam， expounds its structure design and construction method， and sorts out typical vegetation in each vegetation zone in loess plateau mining area.The slope ecological restoration is carried out by type of shrub vegetation community and multi-stage platform ecological restoration is carried out by trees.The results show that： vegetation planting support technology by using PVC plates lattice anchor beam improves traditional construction technology with its simple structure and construction procedures， in which， on basis of integrity of structure， with small weight， good landscape effect and high rate of vegetation recovery rate， it is not only effective in slope protection but also in slope stability， which is promising in future in application.The research results are of great significance for further revealing mechanism of planting support technology of PVC plates lattice anchor beam， researching ecological restoration and management of slope in loess plateau mining area， and realizing sustainable development of regional economy in loess plateau mining area.
