基于高次团粒喷播技术的某露天矿边坡 绿色生态支护研究

露天矿山开采过程中形成大量的裸露边坡，受岩层节理裂隙和风化作用以及开采作业的震动等影响，岩石结构和稳定性遭受严重破坏，存在较大的崩塌隐患。且裸露的边坡缺乏水分和有机质，在强降水条件下，很容易出现水土流失，自然生态很难恢复。通过应用高次团粒喷播技术，不仅能够提升边坡的稳定性，同时还能改善边坡的生态环境。舞钢中加矿业发展有限公司经山寺铁矿对区内裸露边坡采用高次团粒喷播技术，经过四个月的施工养护，边坡稳定性良好，绿化效果显著。本文以此项目为研究对象，对高次团粒喷播技术施工要点进行详细探究，以期为类似工程提供借鉴。

Study on green ecological support of slope in an open pit mine based on high-order pellet spray seeding technology

A large number of exposed slopes are formed in the process of mining in opencast mines. The rock structure and stability are seriously damaged due to the influence of rock joints and fissures, weathering and vibration of mining operation, and there are great potential collapse hazards. In addition, the bare slope is lack of water and organic matter, and soil erosion is easy to occur under the condition of heavy rainfall, and the natural ecology is difficult to recover. The application of high-order pellet spray seeding technology can not only improve the stability of the slope, but also improve the ecological environment of the slope. High-order pellet spray seeding technology was applied on the exposed slopes in Jingshansi Iron Mine of Wugang Zhongjia Mining Development Co., Ltd. After four months of construction and maintenance, the slope was stable and the greening effect was remarkable. Taking this project as the research object, the key points of high-order pellet spray seeding technology were investigated in order to provide reference for similar projects.
