Abstract：

In　order　to　reduce　the　pollution　of　the　atmospheric　environment,　the　super　large　coal　storage　warehouse　has　gradually　become　the　main　coal　storage　mode　of　power　plants　and　other　enterprises.　However,　due　to　the　enclosed　structural　form,　volatile　coal　dust　and　coal　seam　volatile　combustible　gas　concentration　is　too　high,　which　resulting　in　increased　risk　of　ignition　detonation.　Therefore,　this　paper　based　on　ventilation　engineering　theory　and　combined　with　CFD　which　focus　on　natural　ventilation　used　in　large　diameter　(D　=　100 m)　circular　coal　storage　dome.　The　impact　of　opening　modes,　opening　positions　and　opening　size　of　super　large　circular　coal　storage　dome　on　ventilated　characteristics　were　also　studied.　The　designed　method　of　ventilated　openings　for　super　large　circular　coal　storage　dome　is　further　proposed.　©　2020,　Springer　Nature　Singapore　Pte　Ltd.
