A new practical methodology of the coal floor water bursting evaluating II:the vulnerable index method

In order to solve the difficult evaluation problems on the coal floor water bursting,on the basis of establishment of the main controlling index system of the coal floor water bursting and application of the multi-sources information integration theory,introduced the principle,the process and the research routine on the coupling methods between the geographic information system(GIS) and the artificial neural network(ANN),or the weight of evidence,or the logistic regression,or the analytic hierarchy process(AHP).The vulnerable index method of the coal floor water bursting evaluation was presented.
