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.

We present the articles of the fourth issue of scientific journal "Mining Science and Technology” (Russia) for 2024:

The purpose of this study is to assess dust concentration at the workplace of a crushing and screening plant operator as part of a special labor conditions evaluation. Dust concentration at the operator's workplace was measured using a standard gravimetric method. The testing was conducted in four stages and lasted 400 minutes, which is 83% of the total work shift duration. Data analysis revealed an exceedance of the permissible dust concentration by a factor of 1.28. The labor conditions class (subclass) was established as 3.1. It was found that the average dust concentrations varied by a factor of 3–4 across different testing stages due to the intensity and direction of air velocity at the production site. Based on the obtained data, dust concentrations at the workplace were predicted according to air velocity at the site, with an approximation accuracy of R2 = 0.95. The presented results can be used to predict dust concentrations at the workplaces of operators at other crushing and screening plants, taking into account individual empirical data collected at each site.

How to Optimize Ventilation in Mines Using Diesel Equipment?

🔹 Problem: Modern mines utilize high-power diesel equipment, significantly increasing ventilation load. Traditional airflow calculation methods overestimate requirements by 50%, leading to substantial costs.

🔹 Solution: Researchers developed a novel methodology based on field measurements of actual emissions and numerical simulation. This enables precise determination of airflow needed to dilute harmful substances to safe concentrations.

🔹 Key Results:
✅ Reduced ventilation costs through accurate emission accounting
✅ Optimized air distribution in mine workings
✅ 3.5× decrease in CO and NO₂ concentrations with proper ventilation

📌 Senatorov V.A. Determining airflow requirements in mine workings based on field measurements of actual emissions from internal combustion engine equipment. Mining Science and Technology (Russia). 2024;9(1):53-59. https://doi.org/10.17073/2500-0632-2024-01-203

💡 Conclusion: Innovative calculation methods represent a breakthrough in cost efficiency and environmental safety for mining operations!
