The long-term mining has formed a large number of high and steep exposed slopes, resulting in the destruction of mountain ecological environment, air pollution, water and soil loss, etc. the task of mine ecological governance is imminent. High-order aggregate spraying technology is widely used in the field of mine ecological restoration. Taking the abandoned mine in the northern mountainous area of Fangshan District as an example, this paper used the high-order pellet spraying technology to carry out the ecological restoration of mine slope, mainly introduced the principle, technical advantages, applicable conditions, construction process and technical points of high-order pellet spraying technology, so as to provide reference for the ecological restoration of similar mines.
