Abstract

The purpose of this paper is to develop new approaches for optimizing the technological flows at coal mines. Based on analysis, the area of the presented approaches application has been outlined for decision-making in mining. The concept is to use graph theory methods and network models for balancing the flows incoming to the mine in the form of resources and the output flows in the form of coal, rock, gas, and water. This improves the overall efficiency of functioning the mining enterprise. A new model is proposed that describes the production activity of the underground mining complex for the delivery of three production components to the surface. These components from the viewpoint of rational resource and environmental management can be considered as factors that may have a negative impact on the level of technological scheme in terms of investing advisability, as well as on the environment. These components are coal, rock, methane gas and mine water. Given their stochastic nature, it is accepted for the mathematical description of the movement processes of coal (С), rock (R), methane gas (G) and water (W) to represent them in the form of flows within some technological system of converters, and including the diversification of mining production. The presented approach can be applied not only at the stage of designing, but also to assess the existing state of the coal mines. Special attention is focused on the development of software for decision-making.

Highlights

The general tendencies as a consequence of crisis phenomena in the global coal industry present new challenges associated not with increasing output or increasing income, but, above all, with maintaining of the enterprise functioning
A problem exists that the mine at the stage of designing is considered as a coal mining enterprise, and not as a link in the system of electrical energy and metal generation
The technological flows of coal mines have a significant impact on the environment, which is important and worth considering

Summary

Introduction

The general tendencies as a consequence of crisis phenomena in the global coal industry present new challenges associated not with increasing output or increasing income, but, above all, with maintaining of the enterprise functioning This is conditioned by the fact that the coal industry requires a large amount of resources, and at the stage of designing, it is necessary to take into account parameters that are not completely interrelated. Coal, and by-products in the form of rocks, gas and water should be taken into account in the proposed model This will allow to comprehensively consider the problem of searching for the optimal solution at the stage of designing, as well as when assessing the prospects of a coal enterprise. The above problems require answers to questions: – What should be done to stabilize the state of coal enterprise? How to balance the technological flows of the enterprise? What tools and what is the procedure for implementing? The answers to these questions will be presented in this research
