METHOD FOR RECLAMATION OF LIMESTONE QUARRIES DURING CONSTRUCTION OF INDUSTRIAL STRUCTURES Russian patent published in 2006 - IPC E21C41/32 

FIELD: mining, construction engineering, possible use during technical reclamation of quarry pits.

SUBSTANCE: method includes extracting the quarry field, forming paired stopping walls in extracted space of quarry field, filling the space between paired stopping walls by construction wastes, while preserving full height of draining and ventilation channels, and building a ceiling. After extraction of quarry field, present hanging sides of quarry walls are collapsed to impart required verticality to them, flexible longitudinal links are attached to quarry walls with following guniting of quarry walls with solidifying solution across whole perimeter of extracted quarry space. Then, quarry bottom is evened out with following densification by means of rolling with appropriate machines and devices, after that wells are drilled in soil by means of washout and soil is mixed with solidifying solution, then reinforcing cage is mounted therein with simultaneous feeding of concrete mixture for making iron-concrete pile in soil-cement cover, while diameters of soil-cement covers overlap one another, creating a foundation having increased filtration and hardness characteristics, paired stopping walls are built along perimeter of quarry, letting flexible longitudinal links through them with their following attachment inside paired stopping walls, and columns are set up to make a ceiling.

EFFECT: expanded area of possible use of extracted and reclaimed quarries, for example, for further industrial construction.
