Grey Relation Analysis of Coal Mine Gas Accidents and Its Influence Factors

摘要

Using grey relation analysis theories and grey relation space of multidimensional reference data rows, comparing rows of main characteristic index and the factor index of the coal mine gas accident have been set up. Then its relation coefficient and relation degree is computed. The quantity of the dynamic state trend of the coal mine gas accident is analyzed. The inference degree by dissimilar factor and the sensitivity and relation degree of various influence of coal mine gas accident are given. According to the relation degree, the disaster-causing factors are analyzed predominantly. Most important of all, a support is provided for guiding the coal mine production and safety management.
