METHOD FOR CREATION OF SUSTAINABLE FOREST ECOSYSTEMS ON DUMPS FORMED DURING DEVELOPMENT OF COAL DEPOSITS BY OPEN METHOD Russian patent published in 2020 - IPC E21C41/32 A01G23/00 A01B79/02 

FIELD: mining.

SUBSTANCE: invention relates to mining and can be used in biological reclamation of dumps of coal industry, is aimed at restoration of forest ecosystems on dumps formed during development of coal deposits by open method. Method for planting Scots pine seedlings during combined sowing with perennial grasses on dumps of overburden rocks formed during development of coal deposits by an open method. Method includes landing on dumps of Scots pine with annual seedlings with closed root system in a wide-row method with a planting rate of 400–600 plants per 1 ha and subsequent stripwise sowing of perennial grasses having positive (in rows) and adaptive (in spacing) response to phytogenic field common Scots pine.

EFFECT: technical result is creation on dumps of nature-like forest phytocenosis with high life status of excavation stands, early and abundant seed production, developed grass cover with predominance of species in projective coating, having a positive and adaptive reaction to the effects of phytogenic pine fields, uniform arrangement of reliable undergrowth, expressed vertical stratum and horizontal differentiation.
