摘要
使用SAS软件系统对枣庄矿业集团滕南煤田的煤质数据(全水、灰分和发热量)进行回归分析,并分别提出了利用Ad计算Qgr,d和Aar、Mt计算Qnet,ar回归方程,方程精度达到了不同实验间的再现性临界差的要求。
The coal property data （Mt, Ad, Q） of Tengnan coalfield of Zaozhuang Mining Group are analyzed with SAS software system, the regression equations of Qgr.d calculated by Ad and Qnet,ar calculated by Aar and Mt are individually put forward, the accurace of the equation meets with the requirement of reproducibility critical difference in different laboratories.
