Evaluation on spontaneous combustion tendency of sulfide ores based on entropy and set pair analysis theory
摘要
Abstract
The theories of entropy and set pair analysis were combined to establish a new model for evaluating spontaneous combustion tendency of sulfide ores. The oxidation increment of samples at ambient temperature, self-heating point, and self-ignition point were chosen as the basic evaluation indexes. The weight of each factor was determined from the avail value of data reflected by the entropy, and the subjective problems were avoided. The expression formula of connection degree between every sample and the appraisal criterion was obtained. Based on the relationship between the test values of evaluation factors and different levels of the standard threshold, the samples were ranked through the identity, difference and antagonism of set pair analysis. Then the index connection degree and comprehensive connection degree were obtained, and the samples were further classified. Spontaneous combustion tendency of 10 samples from a typical metal mine was evaluated by this new model. It is shown that the evaluation results are consistent with the factual, so this method is effective and objective for evaluating sponataneous combustion tendency of sulfide ores.关键词
