It is necessary to exactly classify the evaluating indicator of colliery security management, and the classification is also the foundation and prerequisite of colliery security management and evaluation. In this paper, reasonable classification to colliery security management and evaluation is carried by the method of grey incidence cluster. Grey incidence cluster is one kind of grey cluster evaluation in grey system theory. On the basis of lots of investigation, analysis and summary, sample nine coal mines, 13 safety management evaluation, calculate their gray absolute degree, taken given threshold r=0.75, classify these indicators appropriately to simplify the evaluation and examination indicator. Evaluating indicator cluster method is simple and convenient and has the character of strong applicability.
