Abstract
Tramcarsareusedastransportequipment,especiallyinthecentralareaofamine.Asobstaclesinthecloudofpre-
mixedgas,theyproducestimulatingeffectduringthemethaneexplosionaccidentsincoalmining.
Basedonconditionsofcoalminingprocess,asetofmodelsisbuiltforthenumericalsimulation.
Thechemicalreactionmechanism,thermodynamicsofexplosionandelementary
reactionaretakenintoconsiderationinthesimulation.TheTVDschemeisusedfornumericaldiscretization.
Theresultshowsthechangesofshockwaveandfireflamebecauseoftheinfluenceof1to3
