Application of high-order aggregate spray seeding technology in ecological restoration and treatment of exposed rock slope

The high-order aggregate spray seeding technology is a kind of technology that uses special equipment for spray seeding construction on the slope of exposed rock mass.The technology has good slope greening effect, strong soil consolidation and slope protection ability, high construction efficiency and good ecological restoration effect.A mine in Shaanxi is a granite mountain mined for many years.The environment in the abandoned mining area is seriously damaged and the geological environment problem is prominent.Based on the introduction of high-order aggregate spray seeding technology, according to the ecological restoration and treatment of waste slag slope in an abandoned mine environmental treatment project in Shaanxi, combined with the hydrogeological and engineering geological conditions in the mining area and the application of traditional methods, this paper compares and analyzes the effects and benefits of high-order pellet spraying technology before and after the implementation of this project.The results show that the application of high-order pellet spraying technology can effectively improve and restore the ecological environment in the mining area, and the greening effect is good.When the slope is greater than 60°.The rock slope has good soil consolidation function, good plant planting effect, obvious community effect and stable ecological barrier function.Compared with the traditional method, this technology is more environmentally friendly, with high survival rate, low construction cost and strong ability of slope protection and soil consolidation.The proportion of the materials used in the project is similar to that of the materials used in the project, which can adapt to the local climate and provide good economic benefits in the implementation of the project.
