Safety Comprehensive Assessment of Tailing Reservoir Based on Information Entropy and Fuzzy Mathematics

The tailing reservoir is a large dangerous source of manmade mud-rock flow with high potential energy, and the loss caused by tailing disaster is considerably serious. Some basic theories of fuzzy mathematics are illustrated in this paper. In allusion to the present situation of tailing reservoir assessment, this method is tried to apply in safety comprehensive assessment of tailing reservoir. The safety assessment index system is established A new method of calculating index weight is put forward: referring to entropy theory, an entropy model which can evaluate the quality of information given by evaluation specialists is established, to amend the index subjective weight given by specialists through analytic hierarchy process. The primary and comprehensive assessment is given in turn, the safety level is gained at last. A case study is given and the results shows, the method is scientific and effective.
