Abstract

Abstract: According to the characteristics of unascertained information in coal mine gas prevention and management system, factors affecting coal mine safety control were ientified to reflect the overall status of coal mine gas disaster prevention and control, and a safety evaluation index system of mine gas prevention and management system was established. Based on the unascertained measure theory and method, according to the uncertainties in the index system, weighs of the indexes were determined by using the analytic hierarchy process, and the unascertained measure vector of each evaluation index was quantitatively analyzed, an unascertained measure function vector model was built,according to the confidence of recognition results, and the evaluation level was determined .The model was applied to a certain coal mine in Xinjiang.The practice shows that the model can fully utilize the uncertain information contained in the research question, combine qualitative analysis with quantitative analysis, and be used to otain evaluation results conforming to the reality.

Key words: prevention and management of coal mine, unascertained measure ment, credible degree recognition, index vector, safety evaluation
