AI Technical Summary
The slopes of open-air mining sites are prone to soil slipping and collapse in harsh environments such as heavy rain, resulting in safety hazards. Traditional protection methods such as steel mesh and green dustproof fabrics cannot be effectively protected for a long time.
A slope protection device including a protective frame and plant potted plants was designed. The protective frame consists of fixed anchor rods, frame outer frame and frame partitions. Plant potted plants are placed in the frame holes, and the soil is fixed using the plant root system, combined with the anchoring effect of the protective frame, to improve the stability of the slope.
The anchoring effect of fixing soil and protective frames through the plant root system significantly improves the stability of the slope, reduces the risk of loosening and sliding, thereby effectively reducing the risk of slope structure collapse.

In traditional technologies, steel mesh or green dust-proof geotextiles are often used to cover the slopes of the mine for protection. However, with the natural aging of the surface due to wind, sun, snow, rain, day after day, and year after year, these protective measures cannot achieve the essential safety effect of slope protection and management. Therefore, it is necessary to solve the problem of slope protection in mining workshops, especially open-pit mines, and to develop a slope protection device that meets the harsh on-site environment to eliminate safety hazards in metal mine mining areas.
