ABSTRACT
This part describes the deterministic modeling of the mining excavation ventilation process.
The excavation was located at a depth of over 900 m, hence the pressure in it was little higher than the atmospheric pressure. The ventilation process, however, was different compared to that in a submarine, because the ventilation was forced by the release of gas inside the chamber, and the ventilation stream came only outside the chamber and was not directed to the surface. Hence, this process can be regarded as isobaric ventilation.
The described measurement results for ventilation processes presented here demonstrate extraordinary compliance with the theoretical model. Previously, the results that did not show less compatibility of the theoretical model with the results of measurements were recorded several times.
It can be stated that the results of the research on such a large and complex object as a mining excavation are surprisingly consistent with the proposed mathematical model. This suggests that the approach used to model the ventilation process for a mining excavation is sufficiently accurate to predict its course at the assumed level of credibility, thus enabling its practical use for designing mine refuge chambers.
