Abstract: Based on the basic principle of ecosystem theory，the concept of non-coal mine safety management ecosystem is put forward，the non-coal mine safety management ecosystem model is established，and the connotation and structure of the system is analyzed.With the combination of the dissipative structure theory to construct the system evaluation model，the total entropy of the system is calculated and the stability and order of the system are evaluated according to the size of the total entropy.A non-coal mine from Shaanxi Province was selected as a case，and the data of the entropy change index factor of the safety management ecosystem in 2007~2016 were analyzed.The results showed that the evaluation results obtained by the entropy weight method are relatively reasonable，which provide an important basis for monitoring and targeted governance of the relevant departments.The accumulated information entropy of the system from 2007 to 2013 is positive and the system is In the case of chaos，while the accumulated information entropy of the system is changing from positive to negative from 2014.The system tends to be stable and orderly from 2014 onwards.
