4.2 Typical techniques of mine vegetation restoration
4.2.1. Vegetation growth rolling cover method and high and steep rock slope greening method
The vegetation growth rolling method is mainly applied to the soil slope with slow slope and low slope, and the local turf is used for planting. It can form target population in a short time.
The greening method of high and steep rock slope is mainly through planting the substrate of sustainable growth of vegetation on the surface of mine slope. The matrix is fixed on the surface layer of rock slope after mining excavation for a long time. At the same time, according to different geological conditions, the vegetation species selection and outdoor growth experiment were carried out by using the solid soil slab structure made of waste straw to ensure the greening effect of high and steep rock slopes.
