Regression for coal moisture,ash yield and calorific value with SAS software

ZHUANG Yan(Transportation and Sales Department of Zaozhuang Mining Group Corporation Ltd.,Zaozhuang 277000,China)  
The coal property data(M_t,A_d,Q) of Tengnan coalfield of Zaozhuang Mining Group are analyzed with SAS software system,the regression equations of Q_(gr,d) calculated by A_d and Q_(net,ar) calculated by A_(ar) and M_t are individually put forward,the accurace of the equation meets with the requirement of reproducibility critical difference in different laboratories.
