多煤层煤质分析法研究

Study on multi-coal seam coal quality analysis method

为了优化选煤过程中的煤质分析方法,以提高煤的经济效益,以东欢坨矿井选煤厂为对象,通过多层煤质分析方法将性质相似的煤层进行同一化处理,并与传统分析方法的优缺点进行对比,发现对于工业指标、粒度组成和浮沉物组成相似性质的煤层可共用同一煤质资料进行分析,相较于传统的逐层加权分析方法,简化后的分析法可以大大提高分析效率,减少分析误差。

In order to optimize the coal quality analysis method in the process of coal preparation to improve the economic benefits of coal,the coal preparation plant of Donghuantuo mine is taken as the object.The coal seams with similar properties are homogenized by multi-layer coal quality analysis method,and compared with the advantages and disadvantages of traditional analysis methods.It is found that the coal seams with similar properties of industrial index,particle size composition and float-sink composition can share the same coal quality data for analysis.Compared with the traditional layer-by-layer weighted analysis method,the simplified analysis method can greatly improve the analysis efficiency and reduce the analysis error.
