Abstract
The creation of components for iron ore concentrate during the initial mixing stage is accompanied by the formation of suspended particles, including both mining dust and dust from prepared components of the iron ore concentrate. This process poses a significant challenge in terms of safety and health for workers involved in the production, as well as equipment integrity. Various methods are employed to mitigate airborne dust, such as the installation of filters, ventilation systems, and other technological solutions.
The application of pulsating ventilation can be an effective method to combat dust in agglomeration mining. The combined use of pulsating ventilation and liquid spraying allows for more efficient dust capture and deposition during the transfer of mining components, thereby reducing the risk of equipment breakdown, worker illnesses, and improving production safety in relation to dust-related factors.
This article presents a description and the results of a dust deposition experiment. Since liquid aerosol spraying is used in mining operations, experiments were conducted to compare dust deposition with liquid spraying and pulsating ventilation. The experiment determined the dust deposition time for spraying and the combined use of spraying and pulsating ventilation. To assess the effectiveness of the experimental dust deposition method, average dust concentration dependencies were constructed under various conditions.
