In the era of big data environment,a large amount of data in thermal power plant is stored in the database and cannot be fully utilized.Because of the complicated process of the double inlet and double outlet mill system,the mathematical model is difficult to build.A method of modeling based on data mining is presented.The actual operation big data which impact the coal mill material is extracted.First, the K-Means clustering is used to delete outliers,and then the principal component analysis(PCA)is used to complete attribute reduction,at last the distributed support vector machine(D_SVM)is used to build a model on the Hadoop platform in MapReduce framework for the parallel computation.The results show that modeling time is greatly reduced due to the use of the method,and the accuracy and applicability of the model are very high. Therefore the model can be used to represent the actual material properties.
