METHOD OF KARST FUNNEL WALLS REINFORCEMENT Russian patent published in 2020 - IPC E02D3/12 

FIELD: geomorphology.

SUBSTANCE: invention relates to geomorphology and can be used for reinforcement of walls of karst funnels, and for a long period of time with complete filling of cavity of karstic funnel with mineral mushroom rock for elimination of karst funnels. Method of reinforcing walls of karst funnel using fungus spores involves applying at least one layer of substrate on open surface of karst funnel, including mixture of dolomite flour, shavings, clay and moss. Spores of the fungus are sprayed on the surface of the substrate at concentration of 0.15 kg/m² to 0.30 kg/m² and the substrate moisture content is maintained at level of 10–20 % until the primary deposition of calcium by spores.

EFFECT: technical result consists in providing reinforcement of karstic funnel walls to prevent its further expansion and collapse, and for a long period of time with complete filling of the cavity of the karst funnel with mineral mushroom rock - elimination of the karstic funnel, in the range of equipment for reinforcement of karst wall funnels.
