The invention relates to mining and construction business and can find application in technical reclamation career grooves, remaining after the extraction of building stone and other subsurface minerals.

A known method of reclamation of quarries (1), which consists in forming by dumping refractory walls across career and longitudinal crosspieces with filling the space between them waste production. The disadvantages of this method include the inability to use career extraction for industrial construction, i.e. the subsequent construction of various facilities in existing underground the bowl.

A known method of reclamation of quarries (2), selected as a prototype, including the formation of paired refractory walls across career with the installation of drainage and ventilation channels, the construction of longitudinal ridges, filling the space between the paired walls and longitudinal ridges waste production. The disadvantage of this technical solution is a narrow use, i.e. use as a tank.

Object of the invention is the expansion of applications developed and remediated pits formed in the exploitation of mineral deposits, for example, to further the industry is slowly building.

This is achieved by the fact that in the method of reclamation of limestone quarries, including the development of career fields, the formation of paired refractory walls in the developed space career field, filling the space between the paired resistant wall construction waste, leaving the entire height of the drainage and ventilation ducts, and construction overlap. After developing career fields produce the collapse of the existing hanging the sides of the walls of the quarry to provide the necessary vertical position, fixing of wall's career flexible longitudinal ties with the subsequent filling of the walls of the pit hardening solution around the perimeter of the goaf career, then align the bottom of the quarry with its subsequent compaction by rolling sealing machines and mechanisms, and then drilling a borehole in the soil through erosion and mixing of the soil hardening mortar, then put them in the armature frame with simultaneous supply of concrete mixture for the formation of concrete piles in the ground-cement shell, and the diameters of the ground-cement shells overlap, creating a Foundation with enhanced filtration and strength characteristics, paired resistant wall erected around the perimeter of the quarry, passing through them, the flexible food is performance communications connection with their subsequent consolidation on paired resistant walls, as for the formation of the overlapping set of columns.

Rekultiviruemye thus further career can be used for the construction of vegetable stores, losaltos, freezers, etc.

Savings are apparent during construction and operation due to the savings necessary to isolate such industrial structures.

As construction waste use accidents burnt brick, concrete, reinforced concrete, ceramic tile.

When using a developed career for industrial and civil construction, it additionally erect artesian well.

The drawing shows the underground structure.

Method of reclamation of limestone quarries in the construction of industrial buildings is as follows.

After the end of mining operations for the extraction of building stone manufacture of planning work, then a career in the bowl 1 knock hanging sides, giving the walls 2 career 1 required vertical position. Fixed in the walls of the flexible transverse links 3. Put on the wall of the pit, a layer of shotcrete 4. Then align the bottom 5 career and seal it with sealing machines and mechanisms. Next, form the Foundation 6 by drilling a ground-cement wells 7 with simultaneous installation in her concrete piles 8 th is blowing concreting. Drilling in the ground is carried out by immersing in a ground monitor that through a nozzle jet hardening solution provides erosion and mixing soil. After reaching the design depth of the well remove the monitor and install the armature frame and simultaneously serves under pressure into the well of the concrete mix to fill the resulting space. With reinforced ground-cement piles placed in close proximity to each other, thus forming the cutoff barrier. At the same time establish an artesian well and construct a drainage and ventilation system (not shown). After a few days, after the completion of the solidification process of joint ground-cement piles 7 and reinforced concrete piles 8, produce a Foundation pouring a solid concrete layer 9. Only after the final drying of the Foundation put a layer of waterproofing 10. Then parallel to the walls of the quarry form a pair of thrust wall 11, passing through them, the flexible cross connection 3 with the further consolidation of paired resistant walls. As the erection of a pair of hard walls the space between them is filled construction waste 12 in the form of broken brick, ceramic tile, concrete, reinforced concrete, using for this difference is the main kind of carriers, racks, etc. and Then in accordance with the General plan establishes the required number of columns 13 and erect overlap 14.

The use of the proposed method of reclamation of limestone quarries in the construction provides the possibility of underground structures, including tanks for storage of oil and oil products, gases, warehouses for storage of vegetables, fruits, grains, losaltos, freezers, and when you consider that the recovered surface above the underground structure can be used as arable land, pasture, it is obvious that the effectiveness of the proposed method of reclamation of quarries. It is also obvious that the cost of these facilities will be significantly less as goaf already established operational activities.
