We present the articles of the first issue of scientific journal "Mining Science and Technology” (Russia) for 2025:

Scientists conducting research at the mines of the VVerkhnekamsk potassium-magnesium salt deposit (VPMSD) discovered an interesting pattern: gas-air surveys show that the volume of gaseous impurities in the main ventilation drifts is often significantly lower than in the working areas of dead-end workings. This phenomenon of decreasing gas concentrations along the ventilation airflow path is explained not only by the dilution of impurities due to fresh air leaks but also by the chemical neutralization of gases through interaction with the potash rock mass. Previously conducted laboratory studies confirmed the ability of sylvinite (NaCl + KCl) to absorb toxic and combustible gases. This paper presents the results of field studies at one of the VPMSD mines, where the dynamics of gas impurities in the workings were studied, taking into account both chemical processes and ventilation factors. Specialists measured the concentration of combustible and toxic gases in seams of different mineral compositions and analyzed the influence of potash salt properties on the gas composition in long dead-end workings. Laboratory analysis of the collected air samples, performed by chromatographic method using the "CHROMOS GH-1000" instrument, made it possible to quantitatively assess the contribution of gas neutralization and dilution processes to the reduction of harmful impurity concentrations. The results showed that in long dead-end workings of seam AB (100 m or more), the content of gaseous impurities consistently decreases as the distance from the dead end to the mouth of the working increases. The study also examined other factors influencing changes in the gas composition in mine workings.
