FIELD: mining industry.
SUBSTANCE: method includes extraction of mineral resource by underground mine method in liquid environment, under protection of water-resistant rock massif. Full flooding of auxiliary extracting and preparatory mines is performed, which provide for start of wiping operations, with working liquid, neutral relatively to mineral resource and enveloping rocks and being under pressure, matching value of pressure at depth of mine. Process of removal of separated rock beyond underground flooded space is synchronized with replenishment of working liquid volume in this space. Working liquid pressure can be formed by effecting it with force liquid, which is placed either in mine shaft, hydraulically connected to lower flooded auxiliary extracting mine, or in mine shaft and force column, placed on earth surface, above mine shaft, and hydraulically connected thereto. Required height of force liquid column is determined from mathematical expressions. After mineral resource extraction is finished within mine field, flooded extracted space is used for placement of toxic and non-toxic wastes of industries or strategic objects, while process of transfer of wastes or strategic objects into liquid environment is performed synchronously with removal of working liquid beyond flooded space in volume, equal to volume of transferred wastes or strategic objects.
EFFECT: higher safety.
