Analysis of Experimental Techniques for Measuring the Bonding Index of Bituminous Coal
In order to accurately measure the bonding index of bituminous coal,optimizing the undergraduate experi-mental teaching process.A comprehensive evaluation of experimental errors was conducted based on national standard analysis and testing procedures,including coal sample preparation,coal sample mixing and briquetting,coking and drum experiments,etc.,providing a theoretical basis for accurate and efficient testing of the bonding index of bitumi-nous coal.Starting from the actual engineering background,explore changing traditional confirmatory experimental teaching into open experiments,stimulate students'subjective initiative,and improve the quality of experimental teach-ing.
