As　the　mine　ventilation　system　becomes　increasingly　complex,computers　are　commonly　applied　to　resolve　the　mine　ventilation　network.　Algorithm　is　the　key　of　the　program　operation.　It　is　important　to　develop　an　algorithm　that　resolving　complex　wind　network　efficiently.　Based　on　an　in-depth　study　of　the　loop　method,analyzing　the　shortcomings　of　current　ventilation　network　resolving　algorithms,The　principles　of　the　loop　airflow　method　and　the　Scott-Hinsley+Seidel　method　are　described　in　detail.　The　main　steps　of　the　algorithm　include　“determining　the　wind　network　structure”,　“assigning　edges　and　selecting　the　minimum　spanning　tree”,　“circling　the　independent　loops”,　and　“solving　the　network”.　Kruskal’　s　method　for　selecting　the　minimum　spanning　tree　is　easy　to　understand　and　convenient　for　the　implementation　of　computer　programs.　The　trial-and-error　method　was　used　to　draw　independent　loops,　eliminating　the　need　for　secondary　solutions　for　recurring　subproblems.　The　improved　Scott　-　Hinsley　method　is　used　for　air　quantity　solving　to　make　the　calculation　converge　faster　and　improve　the　execution　efficiency　of　the　algorithm.　According　to　the　algorithm　steps,　a　program　block　diagram　was　designed　to　optimize　the　algorithm.　This　algorithm　is　capable　of　providing　guide　for　the　mine　ventilation　design　and　system　modification　practices.　©　2024　Editoral　Office　of　Mining　Safety　and　Environmental　Protection.　All　rights　reserved.
