To　solve　the　problems　of　generating　emergency　alternative,　an　emergency　decision　method　based　on　evidence　reasoning　with　considering　total　superiority　degree　is　developed　from　the　case　matching　and　case　selecting.　According　to　the　retrieval　method,　the　similarities　between　source　case　and　historical　case　are　calculated,　and　the　historical　and　current　implementation　effects　of　alternative　are　obtained.　Then,　the　evidence　reasoning　is　used　to　combine　emergency　evidence.　By　the　way,　the　total　superiority　degree　of　cases　can　be　calculated,　and　the　most　effective　alternative　is　obtained.　Finally,　a　coal　mine　emergency　decision-making　case　is　given　to　illurstrate　the　feasibility　and　effectiveness　of　the　proposed　method.　©,　2015,　Northeast　University.　All　right　reserved.
