Recovery method of mined-out pits for construction of cemetery-museum

FIELD: mining.

SUBSTANCE: recovery method of mined-out pits involves filling of the worked-out area to the boundary of upper level of ground waters with construction waste close as to its composition to natural minerals, laying of drainage layer of construction waste with thickness of not less than 0.6 metre and with fraction size of 150-200 mm. At that, first, planning is performed and cuts of deposits of average coal age are determined. Filling with construction waste is performed while those cuts of deposits of average coal age are kept free, and access is provided to them in order to monitor them and to arrange the museum of the Earth. Then, in the centre of the pit, on the drainage layer there laid are overburden rocks; at that, a hill is formed; after that, when the hill height reaches average absolute level, terracing of hill slopes is performed by means of a bulldozer; and section is pre-broken and furrows indicating the boundaries of the future terraces, tracks and access ways are ploughed. Bed of each terrace is formed with reverse cross slope to two gradients; at that, width of terrace bed is not less than seven metres. For each terrace, starting from lower tier of terraces, along the whole perimetre of the pit, there built are embankment plate or stone walls and they are bound with cement mortar. Drainage system is routed and burial places are built on terraces.

EFFECT: reducing labour costs of recovery work owing to excluding the necessity of extraction of large volumes of soil for creation of fertile layer.

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, includes 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, laying drainage layer and the layer of fertile soil.

The disadvantage of this method is the extraction of large volumes of soil to create a fertile 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 present invention reduces the labor and cost of the rehabilitation works. For this purpose, the method of restoration of worked-out quarries, including separate recess, the mined-out space to the border of the upper level of groundwater construction waste, friends of the composition to the natural minerals with different particle size fractions, layers with subsequent compaction of each layer, laying drainage layer with a thickness of not less than 0.6 meter and a particle size fractions of 150-200 mm, according to the invention initially producing the layout and determine the sections of sediments representing the geological nature monument of the tab construction waste is produced, keeping the cuts sediment free, with access to them, monitor them, and Museum of the Earth, then the career center on the draining layer is dumped overburden, thus forming the hill, after the height of the hill you will reach the average absolute marks, produce terracing of the slopes of the hill with the help of bulldozer will first produce a breakdown plot and PROPARCO furrows marking the boundaries of the future terraces, paths and driveways, then bulldozer form the fabric of every terraces with opposite transverse inclination of up to two degrees, and the width of the terraces should not be less than seven meters, then for each terrace, starting with the bottom tier of the terraces around the perimeter of the hill satisfied with retaining walls of the plates or stone and bind them with cement mortar and lay the drainage system, and on the terraces arrange a place for the burial of the remains, the distance from the groundwater level prior to disposal shall be not less than the 2.5 meters, and to ground cloth terraces not less than one meter, in addition, paths and driveways spread of natural or artificial stone. 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, and terracing of slopes career allows you to reap the economic benefits from restoration of disturbed land without considerable cost. Given that that generated construction waste disposed to landfill disposal of household and industrial waste, the implementation of the present invention will improve the ecological situation.

The drawing shows the circuit implementation of this method.

The method is as follows.

First on the area of disturbed land perform planning work. Determine the sections of sediments representing the geological nature monument. The mean 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 Zack is adce developed 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, monitor them, and Museum of the Earth. 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 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, walkways and paths, driveways, form the canvas terraces 5. The construction of terraces 5 given width (C), not less than seven meters with a cross slope of up to two degrees is produced by using the universal bulldozer. To which the blade is installed in its working position, pushing forward the right (sermon) side of the blade. For formation of company name to be cut angle right Shoe pusher bulldozer of preventive the t spherical head down, fixing it in position, so that the knife blade gets the angle in the vertical profile. Then the bulldozer, selecting a relatively flat place to start, goes to the top of the right-of-way land under the terrace, and performing a reciprocating motion on a small stretch of road along the planned terraces, cuts the ground before the formation of the horizontal platform. Cut the ground weakly hurts from shoveling, so a slight turn of the bulldozer have to move it to the left (down the slope), pouring under the left track, and thus to replenish the bulk part of the terrace 5. Having finished the work in this period (length of 10-15 meters), the bulldozer moves forward to a new area and so on until the end of the terrace 5. Then the cycle is repeated with the next terrace. 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. For the construction of retaining walls 6 used plates and stone, and connect them with concrete mortar. To prevent stagnant waterlogging of the soil laid drainage system (the drawing is not marked). On the terraces 5 arrange places for burial of the dead, the distance (a) from the groundwater level prior to disposal (7) Dol is but to be not less than 2.5 meters, and the distance (b) from the landfill to ground cloth terraces not less than one meter. Walkways, driveways spread of natural or artificial 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 produced retaining sections sediments of the middle age free, with access to them, monitor them, and Museum of the Earth.
