Colliery ventilation safety evaluation on the basis of the unascertained measure
-
摘要: 運用未確知測度理論建立礦井通風系統安全評價指標體系,構造了未確知測度模型,計算了各評價指標的未確知測度值．根據置信度識別準則進行等級判定,得出了評價結果．該評價方法能解決礦井通風評價中諸多因素不確定性問題,還能對其進行定量分析．實例表明,用未確知測度評價模型對礦井通風安全進行評價,其計算結果與實際運行情況很吻合．Abstract: A result of safety evaluation was educed according to the rules of credible recognition after a index system in colliery ventilation safety evaluation was established. An unascertained measure model was constructed and the unascertained measure values of all evaluation indexes were calculated. This method can solve a lot of unascertained problems in ventilation system evaluation, and also can analyze the ventilation system quantitatively. Exemplification indicates that the evaluation result is consistent with actual instance if the method of unascertained measure evaluation is applied in colliery ventilation safety evaluation.
