FIELD: environmental protection.
SUBSTANCE: invention relates to the field of environmental protection; it can be used in the liquidation of emergency spills of oil and petroleum products under the ice cover of mainly flowing reservoirs. A method for collecting an oil slick in a localization zone and subsequent collecting in oil receivers is proposed. The method includes the creation of cavities and guide channels in the ice across a water stream at an angle to its dynamic axis using a natural snow cover as thermal insulation, allowing oil spilled under the ice cover to be moved into lanes with subsequent removal. In addition, on the surface of the cleared ice, on the border with snow thermal insulation, it is possible to create recesses for faster and deeper freezing of ice and, thereby, the formation of a more expressed ice channel.
EFFECT: method minimizes the negative impact of oil spill on the environment and simplifies the process of collecting oil spilled under the ice of the flowing reservoir.
