摘要
煤层配比、入洗粒度下限和分选密度是影响段王煤矿选煤厂分选效果的三个主要因素,文章首先采用正交分析法确定主次影响因素,将三因素分析转换为简单的两因素分析。继而采用分类曲线法将繁杂的数据分类转换为直观的曲线图,最终确定了选煤厂的最佳分选条件。正交分析法和分类曲线法的综合运用为多因素影响情况下选煤厂的科学设计提供了新思路。
Firstly,the primary and secondary influencing factors of the coal preparation are determined with orthogonal analysis among the factors of rate of coal seams,lower size limit and separation density,to simplify the three- factor analysis into two- factor analysis. Then, classification curve method is applied to finish the data classification, and determine the best separation conditions of the coal preparation plant. In multi- factors cases,the integration of orthogonal analysis and classification curve is a new idea to determine the best separation conditions of coal preparation plant.
