Risk value judgement of the disaster factors on grey relational analysis

摘要

Fire, one severe disaster of the coal mine, threatens miners lives seriously and hampers the sustainable development of the mine. Current fire disaster evaluation with a strong subjectivity hasn't a perfect evaluation index system. This paper uses grey relational evaluation mode of the grey theory to analyze many non-linear, dynamic factors influenced fire disasters quantitatively and determine the risk value of every factor to develop targeted preventive measures to ensure mine safety.
