Given　the　lack　of　research　on　dust　pollution　diffusion　under　traditional　ore　drawing　operations　in　gold　mines,　Ansys　Fluent　was　used　to　simulate　the　flow　characteristics　of　air　and　dust　pollution　in　the　roadway.　The　results　show　that　the　airflow　state　in　the　main　transport　roadway　is　relatively　stable　and　strong　reverse　air　circulation　develops　in　the　ore　drawing　roadway.　Dust　is　highly　concentrated　in　the　ore　drawing　area　and　moves　to　both　ends　of　the　roadway.　The　dust　discharge　rate　on　the　operation　surface　is　slow,　taking　150　s　for　a　single　ore　drawing　operation　to　meet　the　requirement　of　continuous　operation.　Finally,　a　new　ventilation　and　dust　removal　system　based　on　a　mist　curtain　approach　and　an　intelligent　damper　was　designed　to　maintain　the　airflow　cleanliness　required　by　each　operation　surface　and　reduce　dirty　air　series　connection,　after　application　testing,　the　dust　reduction　effect　can　reach　72.6　%.　©　2024　Elsevier　B.V.
