The viewpoint about how to ensure safety production is expatiated from the aspect of safety management. Several questions that should be solved in mine safety management are discussed particularly firstly in this paper. In second part, with the principle of accident tree, some representative cases in one mine are analyzed, and more thirty laws are educed about the time, places and working procedure that easily make accidents happen, and the conclusion is confirmed by a lot of accident cases happened in our country. In third part, the Five Elements about mine safety are analyzed, they are: the basis is quality standardization, furnishment should be mechanised, management should be strictly based on laws, prevention should be ahead of time, the emphasis is group construction.
