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.
Abstract
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.
