Rock　drilling　of　face　1703　of　section　185　of　the　Ashele　Copper　Mine　was　used　to　study　dust　migration,　control,　and　reduction　during　excavation.　Fluent　numerical　simulation　and　theoretical　analysis　methods　were　used　to　study　dust　pollution　during　excavation.　An　orthogonal　experiment　was　carried　out　to　optimize　the　ventilation　parameters　of　the　excavation　face　and　assess　the　effect　of　the　main　parameters　(the　cross-section　size　of　the　air　inlet　duct,　the　location　of　the　end　face　of　the　roadway　inlet　duct　and　air　inlet　rate　of　the　excavation　face)　on　dust　reduction　and　control.　The　experimental　results　show　that　the　ventilation　parameters　that　were　most　significant　in　reducing　and　controlling　the　dust　pollution　were　the　excavation　face　air　inlet　rate.　A　range　analysis　showed　that　the　most　reasonable　ventilation　parameters　were　an　air　inlet　rate　of　the　excavation　face　of　13　m/s,　the　location　of　the　end　face　of　the　roadway　inlet　duct　of　4　m,　and　the　cross-section　size　of　the　air　inlet　was　0.9　m.　A　comparison　of　the　original　and　optimized　ventilation　schemes　showed　that　the　dust　pollution　in　the　excavation　face　and　the　respiratory　area　decreased　significantly.　The　effectiveness　of　the　optimized　parameters　was　further　checked　through　field　tests.　Finally,　by　dividing　the　activity　areas　of　underground　workers　in　the　roadway　and　further　calculating　and　analyzing　the　dust　concentration　in　the　breathing　area　of　underground　workers　based　on　Python　deep　data　mining,　providing　theoretical　assistance　for　dust　control.
