Abstract
Increasing volumes of consumed mineral raw materials alongside with depletion of their reserves in the regions, where their mining is convenient, and other modern phenomena explain the need to modernize the technologies for the development of mineral deposits. One of the main ways to improve the efficiency of mineral raw material extraction is to manage the mined-out space by filling it with solidifying mixtures. At the same time, the problem of transporting these solidifying mixtures to remote areas of the mine becomes more acute. Existing technologies are limited in their ability to solve this challenge, which significantly increases the costs of mining mineral raw materials. The article describes a relatively new technology for transporting a hydraulic mixture over a distance of 2000 m in the vibration-forced mode, which has been used for a number of years in the underground mining of adjacent deposits with preparation of mixtures at one of the deposits and their transportation to another deposit. The paper justifies the possibility of optimizing the processes of hydraulic mixture movement while minimizing the costs and reducing the environmental impact by constructing a pipeline not on the earth's surface, but in the underground workings. The results of justifying the parameters of hydraulic mixture transportation in the vibration-forced mode are given, obtained by modeling according to the criteria of distance and reliability of transportation and confirmed by practice.
