Natural dynamic ventilation of open mines

The author evaluates the combined influence of the various shapes of near-mine relief and the geometric parameters of the mine on the effectiveness of its natural dynamics ventilation. The problem was solved by modeling with geometric similarity to the scale of 1:1000 and equal wind flow speeds in the model and nature. The empirical expressions that are presented can be used to obtain, for a broad range of relief patterns, a more detailed description of the natural dynamic ventilation of mines depending on their geometric parameters. They can be used to predict the degree of air pollution in an open mine when devising the plan of a new mine or preparing for intensification of air exchange.
