Application of Grey System Theory in the Safety Evaluation of Coal Mines

摘要

This paper makes a compositive analysis to the safety of coal mine with the method of grey correlation analysis in grey system theory. It constitutes a index system and a taxis model of grey correlation analysis which can be used to evaluate the safety of coal mine. The author compares the evaluating results with practical safety situation of coal mine .The results show that grey system theory can be used to evaluate the safety of coal mine.
