VENTILATION OF AN OPEN-PIT MINE THROUGH PIPELINES AND UNDERGROUND MINE WORKINGS
Abstract
This article analyzes artificial ventilation methods in open-pit mines, particularly using pipelines and underground mine workings. The principles, advantages, and disadvantages of blowing and exhaust ventilation methods are discussed. Additionally, ventilation systems based on fans, aviation technology, and thermal devices are examined. Special attention is given to the effectiveness of aviation-based systems, especially the UMP-1 unit. The results show that these methods are most effective for local ventilation of small polluted zones.
