MOBILE UNIT FOR UNDERWATER EXTRACTION OF ORE MATERIAL Russian patent published in 2025 - IPC E21C50/02 E02F3/88 

FIELD: mining.

SUBSTANCE: invention relates to mining and can be used in development of minerals, for example, gold, at the bottom of a reservoir or in development of flooded deposits of solid minerals, developed by a combined open-underground method, in particular, during restoration of an emergency flooded mine or quarry. Mobile installation for underwater extraction of ore material includes an air-cushion vehicle, made with possibility of installation on water surface with possibility to move on its water surface above ore material, and which comprises compressed air source, storage tank with flexible hoses, rod with lever pivoted thereto to support detachable drilling nozzle or soil pump filter connected via flexible pipeline with vehicle compressed air source. Flexible hose for supply of pulp with ore material from drilling nozzle or pulp from filter to storage tank of transport facility is inserted into it tangentially. Accumulation tank is equipped with a flexible hose for discharge of clarified water into the developed mine working and a flexible hose for supply of enriched pulp with ore material to the separator of ore material particles from water. Flexible pressure pipeline for supply of compressed air from compressed air source into drilling nozzle or filter is built-in inside hollow housings of rod and lever.

EFFECT: redirection of energy of movement of air-cushion vehicle into energy of underwater extraction of ore material and transfer to separator of ore material particles from water.
