OPTIMIZATION OF PAPAMETERS FOR EVALUATING STRUCTURE COMPLEXLTY IN COAL MINING

Taking the application of system relational analysis in the prediction of geology structure in Shenmushu coal mine as an example, first of all, the paper discusses the mathematical principle of grey relational analysis and ten assessment indices which have been determinated to express the degree of geology structure. Secondly, it maily introduces a serues of using the method of grey relational analysis,by mean of microcompute Which quantitativelyu assures the relavance value.Proportion amongthe intices and seekes the assessment indices.It is aimed at the gaology strcture in Shanmpshu coal mine, seekint seven indices as saperiority indices and three indices as nonsuperiority indires.
