摘要
在研究西山煤发热量与工业分析指标相关性的基础上,对西山矿区9个矿井的烟煤煤质分析数据采用麦夸特优化算法(Levenberg-Marquardt)进行了回归分析,推导出了工业分析指标灰分和发热量的回归方程,并对其进行了显著性检验,回归方程具有一定的实用意义。
Based on the relations between calorific value and approximate analysis indexes, the regression equations between calorific value and ash of coals from nine mines of Xishan coalfield were obtained using Levenberg - Marquardt method. The regression equations of calculated calorific value and ash are proved having perfect precision, and can be used in Xishan coalfield.
