Xue Jun Zhao, Yang Yang · Advanced materials research · 2013
The construction of green mining is a transformation for mine enterprise management method. The technology innovation ability of Coal mine is a key aspect in green mining selection, and seriously impacting on competition. This paper analyses the data of coal mine which had participated in green mining competition, and gives a more reasonable evaluation rules by decision tree. The main methods process is calculated the information entropy of evaluation index in technology innovation ability, with its numerical size as classification node sort the basis. Through the reasonable form pruning decision tree, complete decision tree corresponds complete evaluation rules. Putting the original coal mine enterprise data into evaluation rules, the correctness of the evaluation rules were verified by evaluation results.
