摘要
分析永定区域无烟煤的煤质实测数据发现，其内水、灰分、固定碳与发热量之间存在着某种线性关联，可对其建立最佳回归方程并对该回归方程进行适用性验证以验证企业交易煤炭质量。
The coal quality characteristics of anthracite in Yongding area were analyzed in this paper. Through the determined data, a linear correlation between the inner moisture, ash yield, fixed carbon and the calorific value was found out to set up a optimal regression equation which could be applied to verify the coal quality in coal trade.
