The object of this study is coals of different stages of metamorphism and the volatile products of their thermal decomposition. Currently, based on the basic genetic signs of metamorphism, there is no reliable regulatory framework for determining the haza... see more

The process of accumulation (stockpiling) and mixing (blending) of coal will produce coal quality in accordance with the specifications you want, but as a byproduct of coal sludge typically generated, air pollution, water pollution,  self combustion ... see more

The article is devoted to the study of the causes and conditions of spontaneous com- bustion of sulphide ores, which may result in endogenous fires that complicate mining operations in mines, causing enormous material damage to the national economy, and o... see more

Grounded technological scheme of energetic module, based on the use of underground energy combustion or gasification of coal deposits.The main elements of the energetic module: 1) waste heat exchanger working levels; 2) channels that combine working level... see more

The combustion of coal wastes resulting from mining is of particular environmental concern, and the importance of proper management involving real-time assessment of their status and identification of probable evolution scenarios is recognized. Continuous... see more

Geographical Information Systems (GIS) are often used to assess and monitor the environmental impacts caused by mining activities. The aim of this work was to develop a new application to produce dynamic maps for monitoring the temperature variations in a... see more

Thermal power plants expel pollutants consisting of hazardous gases that result in degradation of environment and ecosystem, gasification technologies offer potential for clean and efficient energy. To address sustainable power production using coal-based... see more

The possibility of blending acid tar waste with coal as a beneficiation method was explored in this work. It was essential to first establish the material properties of the acid tar and coal samples together with that of the blends in terms of proximate a... see more

Annually, dozens of endogenous fires are recorded in Ukrainian mines. To date, mining and geological factors have not been reliably established that contribute to the development of foci of spontaneous combustion of coal in characteristic places (zones) o... see more
