On Designing Ventilation in Quarries


In recent times, at the quarries one of the main problems is to ensure normal sanitary and hygienic and safe working conditions. This problem is also worsened by the increase in the depth of open pit mining. The regulatory framework for ensuring these conditions is generally established. However, there are still issues that require reasonable decisions. So, the problems of methodical and regulatory support for ensuring the design of quarry ventilation practically remain unaddressed.

Review of the literature sources and regulatory documents, which reflect the design of quarries ventilation, as well as its main stages is presented in the article. Based on the generalization and experience of designing ventilation of many quarries, the stages of such design are emphasized.

On the concrete example it is shown what wrong conclusions are drawn due to lack of scientifically based methodological recommendations for calculating the pollution of quarries at their natural ventilation. For this purpose, using the methods of MGI NITU «MISiS» the calculation was carried out concerning the natural ventilation of one of the mountaintop quarries of the Russian Far North.

As shown by the calculations, the concentration of dust in the worked-out area as a result of natural ventilation with wind directions from the mountain will be within the normal range at a speed of 2.5–3 m/s. At a lower speed, the dust concentration may exceed the maximum permissible, therefore, during these periods it is required to take measures aimed at its reduction. Moreover, it is required in case of calm, when there is a high probability of temperature inversions, especially in the winter period with anticyclones. Thus, the need was confirmed in calculating the concentrations of harmful substances in mountaintop quarries at their natural ventilation, at least from the side of the mountain and in case of calm.

The justified and given in the article proposals are related to the development of relevant intersectoral guidelines for designing ventilation in quarries.
