However, the lack of the abilities to simulate some of the important mine fire phenomena realistically hindered its wide applications. This research carried out to improve and upgrade the MFIRE 2.20 program to MFIRE 2.30. The new additions of MFIRE 2.30 including a time dependent fire model, smoke rollback prediction, the incorporation of a moving fire source, and a rewriting of MFIRE in Microsoft Visual C＋＋ were interpreted.展开更多
