FIELD: mining industry, particularly to develop watered placer deposits and technological mineral deposits under permanent negative temperatures of ambient air.
SUBSTANCE: method involves performing preparation and production works, mineral processing and refuse stacking operations. To implement above method dam is built around mining equipment and deposit to be developed prior to air temperature reduction to negative value; installing sled-mounted hangar having transparent heat insulated roof over the dam and performing all above mentioned works and operations inside the hangar.
EFFECT: increased efficiency of production and processing equipment.
