测定煤体含水率与降尘关系的实验研究

Test and Study of Determination of the Relation between Coal Water Content Rate and Dust-laying Rate

通过在实验室用不同方法调整水份煤样测定产尘率得出的不同结果 ,分析了浸水法和滴定水法产生系统误差的根源 ,得到了测定煤体含水率与降尘率关系的简单而误差小的方法 ,即“滴定水法” ,得到了较好的关系曲线。

This paper,by the different results of dust-generating rates measured with different methods for regufating in laboratory the water contents of coal samples,has made an analysis of the system error source resulted from the soaking method and the titration one,obtaining the simple and least error method—the titration method for determination of the relation between the coal water content rate and the dust-laying rate with a better relaiton curve being made.
