Abstract RU 2166096 C2

FIELD: mining industry; applicable in storage of salt-slime wastes in workings of potassium mines. SUBSTANCE: method includes driving of chambers in stable brine- and water-impermeable rocks surrounding working horizons with leaving of interchamber pillars; driving of air haulage headings connected with chambers by inclines. Floor of air and haulage headings are located above pressure arch formed in possible caving of roof rocks into chambers. EFFECT: higher degree of fullness of chambers due to full use of their volumes. 4 dwg
