New coal dust suppression technologies
The most commonly employed method for controlling coal dust in an air is water spray dust suppression (hydrodedusting). One notable limitation of this method is the coal’s hydrophobic nature, which hinders water from wetting coal dust particles. In order to overcome this, surfactants are introduced into the water to increase the wettability of the hydrophobic coal particle surface.
Researchers on the pages of the journal "Mining Science and Technology" (Russia) proposed a dust suppressant composition consisting of oleic acid, sodium hydroxide, and linseed oil in water. The simplicity of this composition, its minimal impact on the environment and human health, and its negligible influence on the further use of coal raw materials make this wetting agent composition highly promising for application in coal industry technologies of water spray dust suppression.

Artificial intelligence technologies for predicting dust emissions from mines
PM2.5 in OPCMs is a serious occupational hazard to miners’ health. It can cause respiratory, lung, cardiovascular, and cancer diseases. Historical reports indicate that increasing air PM2.5 pollution concentration by 10 μg/m 3 results in an increase in lung cancer rate by 36 %. Meanwhile, OPCM PM2.5 emissions measured in this study ranged 10 to 90 μg/m 3. These are really hazardous levels for the health of miners. Therefore, accurate air PM 2.5 pollution prediction is of crucial importance in terms of occupational health and selecting solutions to reduce OPCM PM2.5 pollution. Researchers proposed the novel HGS-FLNN model for predicting PM 2.5 pollution in OPCMs with an average accuracy of 94–95 %.

Assessment of the efficiency of wastewater treatment from coal enterprises for suspended solids using various filtering materials…

We present the articles of the fourth issue of scientific journal "Mining Science and Technology” (Russia) for 2024:
The problem of biological reclamation was studied in the Kizel Coal Basin area. The effectiveness of reclamation was evaluated on several sulfide coal waste dumps. The reclamation methods, as well as the period of soil-vegetation cover formation, varied. Agrochemical properties of the dump soils were studied using unified methods. The NDVI (Normalized Difference Vegetation Index) was calculated based on Sentinel-2 and Landsat 7,8 images. To assess biological activity, phytotesting was used. The lithostrats ranged from slightly acidic to neutral (рН–Н2О = 6.1–6.8); the embryonic soil showed a slightly alkaline reaction (7.9). The embryonic soil, due to the presence of coal particles, had the highest organic matter content (12–7.7%). Depending on the "age" of the soil, the amount of organic matter in the lithostrats varied: for the 7-year-old lithostrat, it ranged from 2.4 to 8.9%, while for the 4-year-old lithostrat, it was less than 1%. The absorption capacity of the lithostrats was similar to that of the background soil. The dump soils were characterized by low levels of nutrients (NPK), with the 4-year-old lithostrat having the lowest N content. The dump soils demonstrated favorable conditions for plant growth, as evidenced by the height and biomass of cress and oats. The calculated NDVI for all dumps ranged from 0.4 to 0.6, indicating the presence of a stable vegetation cover. The implemented reclamation measures proved to be effective.
