煤工业分析（英文：proximate analysis of coal），通常指测定煤的水分、灰分、挥发分以及由计算求得的固定碳四个指标。煤的水分和灰分的高低可近似地反映煤中无机质的含量，并直接影响煤的质量。
通过理论分析，并结合工业实验数据，优化了不同生产阶段喷煤管调整的工艺指标。
The parameters of the pulverized coal injection pipes in different stages have been optimized on the basis of theoretic analysis and industrially experimental data.
挥发分是煤的工业分析中最重要的一个指标，也是最难测准的一个项目。
The fugitive constituent is an important index in coal's industrial analysis, and also is an item that is hard to be measures accurately.
分析了煤发热量与工业分析指标之间的相关性，建立了数学模型。
A mathematics model are established after analyzing the correlativity between calorific value and indexes of approximate analysis.
