The invention belongs to the field of ecological restoration, and provides a method for restoring an open pit
coal mine
waste dump side slope through a water and soil immobilization material. The method comprises the steps that S1, the side slope is leveled and covered with surface soil; s2, the water and soil immobilization material is combined with
plant seeds to
plant plants; s3,
irrigation; the planting method in the step S2 comprises the steps that after
plant seeds are planted on the side slope, water and soil immobilization materials are laid, and the water and soil immobilization materials comprise a
straw curtain immobilization material, a plant
fiber immobilization material, a gauze
straw immobilization material and a reed curtain immobilization material. Or uniformly mixing the plant seeds with the planting soil, the
humus, the water-retaining agent, the
adhesive and the compound
fertilizer to form the plant-growing plate immobilization material, and then paving the plant-growing plate immobilization material on the side slope of the
coal mine dump; according to the technical scheme, the problems of water and
soil loss and seed loss can be prevented, the
water content of the
soil surface is increased, the
evaporation capacity of the
soil surface layer is reduced, the
germination rate and the
survival rate of the seeds are increased, and the immobilization material is degradable and does not need to be manually cleaned.
