SU1765419A1 - Rock dump slope recultivation method - Google Patents

Abstract

Use: reclamation of slopes of rock dumps during open and underground mining of mineral resources. SUMMARY OF THE INVENTION: Mixed with seeds in a wet state, a potentially fertile soil mass is formed together with seeds in the form of pieces of various sizes, having a dump shape in cross section. Pieces are frozen and served from the top edge of the blade on its surface. Positive effect: the potentially fertile ground mass with plant seeds is distributed on the surface of the slope under its own weight at the calculated points. 1 silt

The invention relates to opencast mining methods and can be used for the reclamation of slopes of rock heaps.

There is a known method of reclaiming slopes, which consists in the extraction of mocks or grooves on the entire surface of the slope, and then spreading soil on the surface. The application of this method allows creating a favorable water-air regime for growing plants on the surface of the recultivated slope. However, this method is laborious, since rock heaps are usually large angles of slopes, on which it is difficult to mechanize the operation of the method.

There is a method of landscaping the surface of land structures, mainly slopes, which include laying on the surface of frozen plates formed from moist material containing a nutrient medium and plant seeds.

The application of the proposed method allows creating a favorable water-air regime for the growth of plants on the surface of slopes, with the complete mechanization of the production process in the manufacture and laying of plates. However, the application of the method is effective in the reclamation of only gentle slopes, the complexity of implementation on steep slopes increases significantly, since there are no means of mechanization capable of moving along the slopes of rock dumps.

The aim of the invention is to reduce operating costs by moving the potentially fertile soil mass along a slope under its own weight.

This goal is achieved by the fact that in the method of reclamation of slopes by a dump of rock, mainly in conditions of negative temperatures, including the mixing of potentially fertile soil mass with

freezing it and supplying this mass to a slope, potentially fertile soil mass mixed with seeds, is formed in the form of pieces of various sizes, having an oval shape in cross section, and the supply of these pieces is carried out from the upper edge of the blade.

The drawing shows a scheme for implementing the method.

The method is carried out as follows.

In the autumn, the potentially fertile soil mass is mixed with seeds and formed into pieces of 1 different size, having an oval shape in cross section. This shape of the pieces will ensure their rolling along the blade slope. The number and size of the formed pieces depends on the particle size distribution of the stored rocks. Thus, the number of pieces of a certain fraction is proportional to the number of pieces of 2 rocks of the same fraction stored on a slope. After the pieces are formed, they are left for the winter so that they freeze and gain sufficient strength to move them along the slope without breaking. Feed pieces 1 are from the top edge of the 3 slope of the blade. Due to the occurrence of segregation, a potentially fertile soil mass formed in the form of frozen pieces 1 under its own weight moves along the slope and is distributed along the slope line according to the grain size distribution.

composition, coarse fraction 4 is concentrated at the bottom, and small 5 - at the top.

In the spring, under the influence of positive temperatures, the potentially fertile soil mass thaws, the pieces are destroyed, forming on the surface of the slope areas of loosened potentially fertile soil mass with seeds inside, which creates a favorable water-air regime for the plants to grow.

The implementation of the method will significantly reduce the operating costs of reclaiming the slopes of rock heaps and increase the safety of work.
