We present the articles of the third issue of scientific journal "Mining Science and Technology” (Russia) for 2024:
Interesting studies have been conducted in the field of assessing the geotechnical stability of rock masses.
Using the calculated ratings, the rock masses of ore bodies and host sediments were evaluated for stability (classes/categories have been assigned), and the optimal method and parameters of workings support were determined. The geotechnical database accumulated during the research process provides the feasibility of calculating alternative ratings such as MRMR, RMi, GSI, etc., without the use of transient equations.
For more information, see the article:

How to control the gas hazard pattern in underground workings after blasting?
Determining the sources of hazardous and toxic substances released into mine air, their gas composition, as well as providing each such source of pollution with the required amount of fresh air are important issues in terms of ensuring normal healthy and safe working conditions for miners. An article published in the journal "Mining Science and Technology" established the time-dependent changes in toxic gas concentrations after blasting, specifically at the working face, in the return ventilation current, and near the booster. In order to assess the reliability of the data obtained, the volume of released carbon oxides was calculated based on the data of gas analyzers and chemical reactions of explosives decomposition during detonation, depending on the types and weights of the explosives.
