“…A significant number of works [7][8][9][10][11][12][13][14][15][16][17] are devoted to the study of natural sorbents and adsorption processes characteristic of phase separation surfaces. Natural sorbents for effective purification of industrial wastewater from dissolved and very fine (colloidal) mechanical particles can act overburden rocks of the developed deposit, with a high specific surface area.…”

The most common purification methods in the coal industry are settling ponds and filtering treatment constructions. But in some cases, the use of traditional methods and schemes of water purification is complicated by the conditions of water discharge or does not provide the required water quality. For example, sharp seasonal fluctuations in the level of discharge and water pollution, a large number of spillways distant from each other and a change in their location during the development and moving of mining operations often make it difficult to use expensive and difficult to operate industrial wastewater treatment plants. Often, mining enterprises have a shortage of land areas to place such plants. In this regard, studies have been conducted aimed at identifying the possibility of water purification from suspended solids by filtering in arrays of coarse rock and semi-rock. Such arrays included, first of all, overburden dumps, various technological dams and embankments, as well as specially constructed filter arrays from mining waste. This article presents the results of studies to determine the location of the filter massif in the open pit “Kamyshansky”.

“…At present, hydraulic dumps, in which pulp of quaternary overburden rock washed out by means of hydraulic mining from neighboring sections was previously piled, are an obstacle for mining a number of sections of commercial coal reserves in Kuzbass [1]. Considering that the mining in such rocks is difficult, especially in hydraulic-mine dump areas far from the pulp discharge point, a new hydraulic mining technology has been developed, including the use of hydraulic dredges for dredging water-bearing unconsolidated clay rocks, as well as water jet and hydraulic dredging units for washing out and dredging loamy rocks, as well as sandy-loamy sand after preliminary loosening them with a dragline excavator [2].…”

Substantiation of rational relationships of main parameters of the rock washing-out process when applying GD-300 hydraulic monitors at Kuzbass open pits

The need to use hydraulic technology for washing out quaternary bedrock, as well as heterogeneous rocks previously piled in hydraulic-mine dumps located above commercial coal reserves, requires the use of modern high-performance equipment. As such equipment, it is advisable to use the new GD-300 hydraulic mining giants – monitors, which are designed, manufactured and tested at Kuzbass open pits. In order to increase the performance of hydraulic monitors at Kuzbass open pits, the following dependencies are determined in the article: changes in the amount of water flow through the hydraulic monitors on the nozzle diameter and the pressure in front of it; changes in the amount of solid rock washed out by the hydraulic monitor ‒ solid flow on the nozzle diameter at various values of the pressure in front of it; changes in the solid flow on the pressure in front of the nozzle.

“…The founders of the concept of sustainable development drew attention to the fact that human activity has already gone beyond the balanced functioning of the Earth's ecosystem. The special importance of the problem of sustainable development is intrinsic to the mining sector of national economy which nowadays is a main source of the environment pollution [1][2][3][4][5] The conclusion about reaching the limits of growth was based on a number of estimates. Thus, despite successful economic growth in some regions, since 1974, the decline in world production per capita began.…”

The essence of sustainable development is that the progress of the current generation does not go against the interests of future generations. In the classical definition, the balance between generations is understood as the balance of needs. However, the word “needs” can be interpreted differently. First, we can talk about the ability to meet the needs in the context of the availability of natural resources. This means that we must leave to future generations the same amount of resources that we have, so that they can meet their needs with these resources. Secondly, we can talk about the ability to meet the needs as a standard of living. This means that for future generations it should be at least the same as the standard of living of our generation. At the same time, it is absolutely not necessary that this be achieved due to the availability of natural resources. For example, we can now invest some resources in the development of human capital and knowledge, and future generations will provide a higher standard of living through the growth of knowledge. Consequently, the factor of human capital, determining the pace of introduction of innovative technologies and moving away from resource-intensive industries, will determine sustainable development in the process of transition to a post-industrial economy.
