 11 The invention relates to cnoco6eu4 for dumping and dumping toxic rocks. There is a known method for the burial of empty rocks, which involves drilling in solid ground large vertical workings in each of which a certain amount of rock is poured. This rock is compacted by vibration or pressing, after which another batch is poured. After filling up the production, its fermentation is fertile; a layer of soil. In order to increase the stability and safety of storing drilling waste at distances separated from each other by a sufficiently large soil mass 11. The disadvantage of this method is the possibility of environmental pollution due to the filtration of ground water from excavated working areas. material, difficulty of technical implementation and low productivity. Closest to the present invention is a method of dumping waste, including laying and compacting, at the bottom and side walls of the recess of a waterproof screen, layering and compacting waste, closing the last two waterproof screens and laying the fertile soil layer 2. However, the known method is characterized by low anti-slip and anti-erosion resistance of the waste dump. The purpose of the invention is to increase the anti-slip and anti-erosion stability of the dump with the disposed waste by creating an optimal hydro-mode. The goal is achieved in that according to the method, which includes forming waste dumps by laying and compacting a waterproof screen on the bottom and side walls, laying and compacting waste layer-by-layer, closing the latter with a second waterproof screen and laying a fertile soil layer before placing the first waterproof screen on the bottom of the recess is placed the drainage layer, and on the surface of the second waterproof screen to fill the fertile soil layer pour a layer of potentially fertile at the same time, watertight dams are formed along the contour of the last layer of bedded rock. Figure 1 depicts the plan rekul-. tivatsionnoy territory after the implementation of the full range of work on the burial and reclamation; figure 2 | section aa in figure 1; on fig.Z section bb in figure 1. The method is carried out as follows. First remove the fertile soil layer from the bottom and sides of the recess. The following order is removed from the fertile soil layer by bulldozers or scrapers, fertile rocks are cut from the side walls of the cavity and placed into a stack along the thalweg beam (ravine), fertile rocks are removed from the piles and stored on the side of the workings for subsequent use for recultivation. . On a but cleaned layer of fertile soil, a drainage layer 1 made of sand, rubble or other material with a high filtration coefficient (more than 10 m / day) is folded over. 1; the first layer with a height of 1.5 m is drained. The subsequent increase in the capacity of the drainage layer is carried out as follows: dump trucks are discharged along the dumped strip, and then the soil is transported by bulldozers and laid on the previously removed strip to the desired level. A waterproof screen 2 of dense clays, such as Neogene, with a total capacity of 2.5-3.0 m with a low filtration coefficient (less than 0.001 m / day) is placed on top of the drainage layer and on the side walls of the mine. Waterproof clays (with a natural weight moisture content of 15%) are deposited in layers of O, 5 m, followed by compaction by rollers to a value of the skeleton density of the soil equal to 1.63 g / cm. In the formed waterproof bed, the riverbed is dumped and the waste rollers 3 (thickness of 3-5 meters) are sealed with rollers / insulated on the final slope of the blade with waterproof dams 4. Dams are also made of dense clays by dumping 0.5 m each and then compaction ice rinks. The dam width is 8-10 m. After dumping the blade to the design marks, the compacted waste overlaps the top with a second waterproof screen 5 made of the same material and using the same technology as the lower waterproof screen 2. A layer of 6 potentially fertile rocks with a capacity of 1.5–3 m (but not less than 1.5 m) is piled over a waterproof screen 5, protecting it on the final slope of the dump with a waterproof dam 4. A fertile layer 7 of soil with a thickness of 0, 4-0.7 m (but not less than 0.4 m). The surface planning of the reclaimed area is carried out with the task of a reverse slope of up to 1-2 ° to prevent. rotation erosion of the slopes of the dumps, and taizhe build in bedrock
