The invention relates to the mining and processing industry and can be used to restore disturbed lands in the construction and energy industries.

There is a method of recovery of disturbed soils (1) in surface mining, including mining, moving and storage in separate tape stockpiles of topsoil and overburden, mining career fields, moving, and packing overburden and topsoil. However, restoration of disturbed lands in this method occurs over a very long period, and the soil exposed to wind and water erosion.

There is a method of recovery of disturbed lands in open field development (2), including separate recess, moving and storage in separate tape stockpiles of topsoil and overburden, mining career fields, mined-out space and its alignment in the overburden with the subsequent placement of the topsoil. The disadvantage of this method is the extraction of large volumes of soil to create the fertile soil layer, which in turn leads to the formation of large areas of disturbed land, rising labor costs and a significant increase in the cost of the rehabilitation works.

The closest-is m solution selected as a prototype, is the way of restoration of disturbed lands in open field development (3) including: separate in the recess, moving and storage in separate tape stockpiles of topsoil and overburden, career development, the mined-out space in layers of construction waste, similar in composition to natural minerals, with compaction of each layer, laying drainage layer and filling layer potential of fertile soil. The disadvantage of this method is the high cost of repair works due to the extraction of large amounts of fertile soil.

The proposed solution provides cost reduction and cost recovery operations.

This is achieved in that in the method of restoring the depleted quarries for construction of structures including separate recess, moving and storage in separate tape stockpiles of topsoil and overburden, career development, the mined-out space at the beginning of construction waste, similar in composition to the natural minerals in layers, compacting each layer, and then the overburden with the subsequent alignment and seal according to the invention, after performing the planning and partial bookmark Rabotnov space career, first, the perimeter of the quarry, intended for construction, at a depth of not less than 1.8 meters, produce amplification of the pit using podavlivaya installation by horizontal jacking reinforcing elements with the formation of the end sections outside the walls of the quarry, then around the perimeter of the bottom of the quarry, under each of the protruding end sections of the reinforcing elements, arrange bored piles with a reinforcing frame and a high grillage intended for the installation of the column connecting the bored pile with end sections of the reinforcing elements, the reinforcing elements are placed at the calculated distance from each other, then make a selection of soil strata in the walls of the quarry between the reinforcing elements and the original set of bored piles, after the establishment of the settlement of the soil and the walls of the formed space, installs a subsequent bored piles with columns, their fastening and fetching the next volume of soil, the cycle is repeated until the education career in the walls of the estimated volume of the room, after a full equipment of underground facilities, build the Foundation on an artificial basis formed by the reinforcing elements for the construction of aboveground facilities. As amplification elements use the whole, and rigidly interconnected at the junction to the design section lengths of steel pipes that are filled with the concrete mixture before or after pressing.

Implementation of the present invention dramatically reduces the cost of rehabilitation services, through the use of the developed career (no need to dig the pit), construction waste, constantly resulting from the reconstruction, demolition and repair of buildings and structures. Given the fact that is constantly generated construction waste taken to landfills for household and industrial waste, the implementation of the present invention will improve the ecological situation.

The proposed method is illustrated by drawings, where figure 1 and figure 2 shows the structural diagram of the implementation of this method and the cross-section 1-1.

The method is as follows.

First PA disturbed area perform planning, and planning is conducted so that one side of the pit was intended for future construction, and the other for device access roads. The mean absolute stamp set with the feasibility study. Then make a preliminary backfilling of the open pit (1) construction waste management (2) layers with different grain size fractions. Each layer is compacted by the compaction method platnium the mi machines and mechanisms. Then occiput quarry (1) layer of overburden (3) to the level of the bottom of the pit for the Foundation of the future construction. The layer of overburden leveled and compacted. In accordance with the constructive arrangement of the reinforcing elements (4) in terms of future structures break their axis. Establish the sequence jacking reinforcing elements and make their marks. Make installation podavlivaya installation (5) and put it to guide the platform relative to the center axis of the reinforcing elements (4). Placed on the Cam platform first section element amplification (4), pre-concreted and produce punching in the wall of the quarry (1) in a given horizontal direction, at a depth of not less than 1.8 meters. Using welded or otherwise rigid connection dock next section element amplification (4) and push into the ground. The cycle is repeated to achieve the required design length (L) of the element gain, while the last section is cut through completely, leave the tail section (f) outside the walls of the quarry. Using concrete pump internal volume of the reinforcing elements concreted mobile concrete mixture on the fine aggregate.

Prodavlivayutsya installation move to the next position of the jacking element amplification (4) and the cycle is repeated. Thus, p is rimetry career, planned for the construction of structures, form an artificial basis for further construction on the Foundation of the future construction. The carrying capacity of the artificial base several times increased due to the formation of the compacted zone of soil around the space with reinforcing elements (4). As reinforcing elements (4) are used as solid and composite rigidly interconnected sections of steel pipes filled with concrete. Then arrange bored piles (6) under each of the end sections (f) of the reinforcing elements (4). In the manufacture of bored piles (6) they establish a reinforcing frame. Head of bored piles (6) raise above the level of the plan for the organization of high grillage. Anchor fittings for fastening the column (7) are in the form zamonolichennymi in the head of the pile anchor bolts (8). Providing a flat surface heads of the piles, they set columns (7), the top of which is fixed with end sections (f) of the reinforcing elements (4). Then make a selection of soil strata on the calculated design height (h) in the walls of the quarry, on the perimeter, where laid the reinforcing elements (4). After each sample, the estimated volume of soil the walls and ceiling of a goaf fix and sampling of soil continue. Formed in the space suit to anitelea premises for subsequent use as underground garages, shops or domestic services.
