METHOD FOR BURYING LIQUID WASTE IN UNDERGROUND LAYER ENVIRONMENT Russian patent published in 2004 - IPC

FIELD: mining industry.

SUBSTANCE: method includes use of penetrable and layers for storing wastes by means of pumping of waste there. For burying also badly penetrable clay layers are used as well as water-resistant ones, by means of creation of compulsory filtering of waste there. Pumping of waste may be performed into one sand layer and pumping of underground waters from the other layer separated from the first one by coal layer, with relation of places of pumping to periphery of burying zone. A hydraulic tearing of layer may be performed here with later pumping of wastes into artificial sand bed formed by hydraulic tearing.

EFFECT: greater capacity of storage in proportion to volume of kept clay layers, higher reliability of holding wastes in given boundaries, rational use of water resources of burying area.
