摘　　要：为准确测定烟煤黏结指数,优化本科实验教学过程,基于国家标准分析测试步骤,从煤样制备、煤样混合与压块、焦化与转鼓实验等方面对实验误差进行全面评价,为精准高效测试烟煤黏结指数提供理论依据。从工程背景实际出发,探索将传统验证性实验教学变更为开放性实验,激发学生主观能动性,提升实验教学质量。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.
