摘要
高次团粒喷播技术是一种在裸露岩体坡面上采用专用设备进行喷播施工的技术。该技术具有较好的坡面绿化效果,固土护坡能力强,施工效率高,生态修复效果好。陕西省某矿山为多年开采的花岗岩山体,废弃遗留矿区内环境破坏严重,地质环境问题突出。本文在对高次团粒喷播技术进行介绍的基础上,根据陕西省某废弃矿山环境治理项目中的废渣坡面生态修复治理问题,结合矿区内的水文地质及工程地质情况和传统方法应用,对高次团粒喷播技术在本项目中实施前后的效果及产生的效益进行了对比分析。结果表明,高次团粒喷播技术的采用可以有效改善和恢复矿区内的生态环境,绿化效果良好;在坡度大于60°的岩质边坡上具有较好的固土功能,植物种植效果良好,群落效应明显,生态屏障功能可以稳定发挥;与传统方法相比,该技术较环保,成活率高,施工成本低,护坡固土能力强;所采用的基质材料配比与当地气候及地质条件相适应,在施工中造成的污染小,应用效果良好,具有较好的经济效益,可以为类似项目的实施提供借鉴。
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.
