FIELD: mining.
SUBSTANCE: method comprises development of chambered ways, formation of soil-ice bodies with specific weight below water specific weight. The development place is divided to areas, and mineral deposit is developed in staggered order. Creating artificial lane at each area the first section area is developed, on its bottom a dome is lowered, the dome is connected with surface by flexible branch. Then in under dome space via the flexible branch water in injected from water layer above halocline layer, after creating the soil-ice bodies in the under dome space, and dome emersion to surface the second area is developed along diagonal from the first area for restoration of its ice surface, then the cycle is repeated till complete field development.
EFFECT: reduced cost and ecological loads due to production works on water basin bed of the Arctic shelf at negative temperatures.
