摘　　要：对14种单种煤进行煤质分析,并采用40kg试验焦炉炼焦。通过SPSS软件建立了煤挥发分、镜质组平均最大反射率、黏结指数、碱度指数与焦炭反应性和反应后强度的多元线性回归方程,所得方程的相关系数分别为0. 964和0. 941,有较好的相关性。Coal analysis is done for 14 individual kinds of coal before coke is made by 40kg test oven.Multiple linear regression equation is created by SPSS,i.e.the relation is expressed between coal VM,mean maximum reflectance of vitrinite,bond index,basicity index and the CRI&CSR,with related coefficients 0.964 and 0.941 respectively,which shows a close correlation.
