The invention relates to the technical reclamation career grooves, remaining after the extraction of building stone and other subsurface minerals.

There is a method of recovery of disturbed lands in open field development [1], selected as a prototype, including separate recess, moving and storage in separate tape stockpiles of topsoil and overburden, the development of career fields, mined-out space to the border of the upper level of groundwater construction waste, similar in composition to natural minerals with different particle size fractions, in layers with subsequent compaction of each layer, keeping the cuts sediments, representing a geological monument of nature, free, laying drainage layer construction waste, of a thickness not less than 0.6 meters and particle size fractions of 150-200 mm, layer fertile soil, forming the centre of the quarry hill through landfill overburden followed by terracing the slopes of the hill and the device on the terraces of places for burial of the remains.

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, to the irrational use of land the x space, rising labor costs and a significant increase in the cost of the rehabilitation works.

The proposed solution reduces the effort and costs of rehabilitation activities, and promotes the rational use of land.

This is achieved in that in the method of restoring the depleted quarries, including the mined-out space to the border of the upper level of groundwater construction waste, similar in composition to natural minerals with different particle size fractions, in layers with subsequent compaction of each layer, keeping the cuts sediments, representing a geological monument of nature, free, laying drainage layer construction waste, of a thickness of not less than 0.6 meter and a particle size fractions of 150-200 mm, forming the centre of the quarry hill through landfill overburden followed by terracing the slopes of the hill and the device on the terraces of places for burial of the remains, according to the invention, on the terraces arrange underground sklepowe structures designed for multiple burials, and each sklepowe building designed with waterproofing, drainage, drainage and ventilation systems, while the ventilation system is further provided with a separate air duct, made in the form of a hollow is the anal, filled with stems of reeds and set in the ground with angle less than 35 degrees in the immediate vicinity sklepowego structures with the possibility of accession by each subsequent burial in scapula construction, with the upper end of the duct is located on the ground surface of the canvas terraces.

Introduction this technical solution reduces the cost of rehabilitation services, through the use of construction waste generated as a result of reconstruction, demolition and repair of buildings and structures, as well as eliminating the need for extraction of large volumes of soil to create a fertile layer. Given that the generated construction waste disposed to landfill disposal of household and industrial waste, the implementation of the present invention will improve the ecological situation. The device on the terraces family sklepowych underground structures will eliminate the looming shortage of land for burial.

The drawing shows the circuit implementation of this method. The method is as follows.

First on the area of disturbed land perform planning work. Define in the space career sections sediments of the middle ages, representing the geological nature monument of the device of the Museum of the Earth. rudnyy absolute elevation (ground level) shall be established with consideration of the feasibility study. The layout of the site comply with planned giving the surface a slight bias towards the General lowering of the earth's surface. Then proceed to the mined-out space career 1, stacking layers of construction waste is similar in composition to natural minerals with different particle size fractions. The tab construction waste is produced, keeping the free sections of sediments, representing a geological monument of nature, with the possibility of access to them and observing them. Each stacked layer compacted by the method of compacting sealing machines and mechanisms. The stacking of layers to produce the upper boundary of the groundwater level 2. Then stack the draining layer 3 of construction debris, similar in composition to natural minerals, thickness not less than 0.6 meter and particle size fractions of 150-200 mm Line it and condense.

Then, starting from the center of the pit 1, produce filling in the dump overburden. When the height of the hill 4 the career center will reach average absolute marks, proceed to the construction of terraces 5. After laying out the plot and propasti furrows marking the boundaries of the future terraces, paths and driveways, form the canvas terraces 5. The construction of terraces 5 given width, not less than seven meters with a cross slope of up to two degrees of production is t using a universal bulldozer. Then, starting from the bottom tier of the terraces around the perimeter of the quarry arrange retaining wall 6 to strengthen terraces 5. Retaining wall 6 prevents the erosion of soil. Then on the terraces 5 equip sklepowe underground structure 7 to create places of burial 8. In sklepowych underground structures 7 are working on waterproofing, make drainage, drainage and vent systems. In the immediate vicinity sklepowych underground structures 7 installing additional hollow duct 9, is filled with stems of reeds, and combine it with the first and subsequent burial. In order to eliminate stagnant zones in the duct 9 is installed with an inclination angle less than 35 degrees, and its upper end is situated above the surface of the canvas terraces 5. Installation of ducts 9 accelerates the mineralization of burial due to the access of air to the graves. Cylindrical or triangular stalks of the cane is strong and durable, have a water repellent effect and provide continuous access of air to the graves. The first burial carried out to a depth of three meters, and the distance from the cover of the last burial to ground cloth terraces shall not be less than one meter. Walkways, driveways spread natural or IP is ostendam stone.

Example. Depleted quarries cement plant near the city of Podolsk, Moscow region opened sections of the deposits of the Moscow stage of the middle division of the Carboniferous system, which is dated to the period Podolsky horizon. In order to preserve the historic and scientific value of stratotype Podolsky horizon tab construction waste is produced, keeping the cuts sediments of the middle age free, with access to them, observing them.
