Justification of new opportunities for the use of the gravitational energy of the earth in underground ore mining with convergent geotechnologies

Abstract

The paper describes R&D project results on justification of a new approach to the induced caving of ore using convergent geotechnologies. In this case, the optimized conditions are created for self-caving of ore in block-structure rock mass based on the evaluated limiting exposed span using, among other things, the Mathews-Potvin stability graph. The ore self-caving design solutions include formation of a density discontinuity in the form of a vertical slit in rock mass, as well as different inclinations of sides of the manmade separation and outlining backfill frames. The authors calculate the potential gravitational energy of the Earth, which is accumulated within the dome of natural equilibrium generated in the course of mining.

On the Issue of the Creation and Functioning of Energy Efficiency Management Systems for Technological Processes of Mining Enterprises

“…In the conditions of the modern approach to the organization of production within the framework of the concept of sustainable development, the tasks of accounting and analysis of energy consumption play a significant role not only in terms of profitability of processes but also environmental safety [14][15][16][17][18][19][20].…”

“…On the one hand, this situation allows mining enterprises, taking into account various geological, technological and weather-climatic conditions, to find their own effective solutions to improve the quality of production [9][10][11][18][19][20][21]. On the other hand, the absence of any formal typification and unification of the description of processes, energy resources, indicators, monitoring, analysis and management methods leads to difficulties in scaling and transferring best practices and solutions between enterprises.…”

“…integrated technological information about the results of their activities, and a set of automated, information and intelligent dispatch control systems (information and control systems, ICS), ensuring coordination and control of the work of technical agents, respectively (Figure 1). However, mining enterprises, both open-cast and underground types, due to the specifics of technological environments, are traditionally characterized as objects with a "problematic" data transmission network [18]. Despite the high relevance, importance and critical need to obtain continuous information about the progress of production work, existing data transmission networks have significant limitations on bandwidth and coverage areas.…”

“…Thus, from the standpoint of the tasks of collecting and presenting data in the information space of the enterprise, it should be borne in mind that at the moment continuous access to a large volume of primary data from terminal nodes is not possible, and, therefore, when solving subsequent tasks of information analysis, it is necessary to take into However, mining enterprises, both open-cast and underground types, due to the specifics of technological environments, are traditionally characterized as objects with a "problematic" data transmission network [18].
