VENTILATION OF AN OPEN-PIT MINE THROUGH PIPELINES AND UNDERGROUND MINE WORKINGS

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.本文针对露天矿山的人工通风方法展开分析，重点探讨采用管道与地下采矿巷道的通风方案。文中讨论了压入式与抽出式通风方法的工作原理、优缺点。此外，本文还对以风机、航空技术及热能装置为核心的通风系统进行了研究分析。研究重点关注了基于航空技术的通风系统的应用效能，尤其是UMP-1装置。研究结果表明，上述通风方法在小型污染区域的局部通风场景中应用效果最佳。
