The paper presents an experimental study on the formation process of burden surface texture on the blast furnace throat and its influence on the radial distribution of gas flow. The study was performed with the application of blast furnaces equipped with a bell-type charging device using radio-isotope means for the control of burden surface texture (profile) and burden surface level, i.e., gamma locators for burden surface texture. The study was carried out under the conditions of an operating blast furnace in an iron and steel plant using a unique GEOTAPS system for automated control of geometric and temperature parameters of burden material surface on the blast furnace throat. The influence of the surface texture on the gas flow distribution was also investigated. The possibility of a self-stabilization effect for burden surface texture and gas flow in an operating blast furnace under suitable conditions was experimentally proven. As a result of the experimental study performed, four ways of energy-saving technology implementation were determined for the control of blast furnace melting based on the data on the burden surface texture and previously unknown regularities of surface layer formation of burden material on the throat of an operating blast furnace with a bell-type charging device. The main idea of the paper is the development of automated control for the radial distribution of burden material and gas flow using actual or predicted surface texture parameters as important intermediate factors that both describe the process and have a significant simultaneous influence on it.

“…Hence, on the one hand, it is necessary to work for maximum implementation of the closed cycle of stock preparation for NPSs [16,17]; on the other hand, it is required to stabilize coal extraction and consumption [18 -20]. That is stipulated by the limited reserves of crude oil and natural gas, forming negative tendencies in the world market, and by the unsolved problems concerning absolute safety of nuclear power stations, and reliable disposal of neutralization of radioactive residues of nuclear fuel [21,22].…”

The paper represents analysis, which have helped to determine tendencies of usage secondary and renewable resources by means of their utilization within the closed ecological complex while implementing integrated cogeneration systems belonging to various sources. Both the current state and prospects of secondary and renewable resources use within the closed complex of a mining enterprise have been considered. Relying upon philosophical approaches as for the formation of a viewpoint concerning responsibility of the modern society to future generations, tendencies to form energy production and energy consumption on the basis of alternative radical technologies have been proposed. The authors have put forward tendencies to change coal mining and coal use while generating the raw material from the abandoned and out-of-balance reserves. Chances to use cogeneration systems by various energy sources have been considered. Formation of the unified power and chemical system to improve economic and ecologic expediency of the proposed measures is the key tendency of energy perfection as well as minimization of impact on the underground mine environment and on the surface to prolong activities of dying mining territories and to reduce social tension.

“…Coal is a non-renewable natural resource that is the most copious and economical fossil fuel resource in the world and it contains almost 90% of fossil fuel energy. Coal is a very affordable and reliable source of energy and it has assumed a basic role in the steadiness and development of the world's economy (Thakur, 2016;Medunić et al, 2018).…”

The purpose of this research is to perform an evaluation of the spontaneous combustion of coal (SCC) in Tabas Parvadeh coal mines in Iran, by using the R70 test method based on a the correlation between intrinsic coal properties and the occurrence of its combustion. Firstly, the coal samples were collected from Parvadeh I to IV, and the intrinsic coal properties of the samples were tested. Then, the R70 test method, as the newest method for assessment of the SCC, was used. In the last step, the correlation between intrinsic coal properties and R70 test values was carried out. The results showed that the B1 seam in Parvadeh II and the C1 seam in Parvadeh III have a high propensity of the SCC. The outcomes appear, an expansion of moisture, pyrite, vitrinite, and liptinite contents enhance the SCC tendency in these mines. The results obtained have major outcomes for the management of this phenomenon in Tabas Parvadeh coal mines.
