Abstract: Causality diagram methodology isa graphical knowledge representation based on probabilism.The application of causality diagram in fault analysis and safety evaluation is discussed. As a new approach to analyze fault of machine equipment in coal mine, causality diagram is applied successfully. The study shows that causality diagram is more effective than FTA in security analysis and evaluation.
