The invention relates to methods for biological reclamation of waste heaps and lands disturbed by open and underground mining. According to the method, composite loamy black earth briquettes are preliminarily made from a mixture of forest loam, black earth and a mixture of wild cereal seeds, each of which is connected with biodegradable jute twine into a stepped tape to form a dumbbell-shaped cassette. The cassette is fixed on the upper edge of the dump slope and pushed down with a push, with the briquette stepped belt being deployed sequentially and evenly distributed over the sloped surface of the slope, which creates special conditions for seed growth and development of plant communities. This results in the creation of sustainable plant communities with minimization of wind and water erosion, which increases the efficiency of environmental management and environmental safety of the facility.
