摘要
影响煤炭浮沉试验准确性的因素有煤样、重液、称量设备、浮沉操作等,通过提高煤样代表性、密度准确性、浮沉操作规范性等措施,可以提高煤炭浮沉试验的准确性。
Analyzed is the various factors that influencing the accuracy of coal float-and-sink test;To improve its accuracy through the experiments such as the representation of coal sample,the proportion of accuracy,norms of float-and-sink operation and so on.
