The invention relates to an elemental analysis method based on large samples for industrial analysis and calculation of coal. In the case of large samples, according to the corresponding relationship between the elemental analysis of coal and industrial analysis, through the industrial analysis data of coal, the linear least square method, nonlinear artificial neural network or support vector machine are used for fitting to calculate the coal Carbon content c, hydrogen content h, oxygen content o, nitrogen content n and sulfur content s, so as to complete the elemental analysis of coal. The invention performs mathematical processing on the coal quality with a large number of samples, and the elemental analysis of the obtained coal has good precision, and the analysis method has low cost. |
