The Application of Grey System Theory on Management of Mine Accident

摘要

Mine accident is a complex control system with multi-objectives, multi-layers and multi-factors.For the complexity of mine accident and lack of theory and experimental data, many researches are focus on these uncertainty questions, and this uncertainty is the characteristics of grey system, which is the reason why grey system theory is used here. Grey relevancy analysis is used to determine mine accident prediction, grey classification is used to obtain the most important mine hazard. The basic content and the method of its application are studied here, the prediction and analysis of mine accident is discussed with grey system theory.
