摘　　要：龙固肥煤在用煤结构优化中的应用研究表明,与其他肥煤相比,龙固肥煤具有低灰、低硫、黏结性强、结焦性好等特点,在现有的用煤结构中具有良好的配伍性,可以任一比例替代其他肥煤,替代后焦炭的灰分、硫分降低;反应性降低,反应后强度提高;抗碎强度提高,但耐磨强度稍有劣化。龙固肥煤可视为用煤结构中的主体煤种,其产地可作为煤源基地。Study on optimization of coal blending constitution with Longgu fat coal shows that, comparing with other fat coals,Longgu fat coal has the advantages of lower ash content,lower sulfur content ,higher viscosity, better caking property, and better compatibility with other coals. It can be used to replace other fat coals at any proportion. The coke produced with Longgu coal blended has lower ash content and lower sulfur content,lower reactivity,higher CSR and higher crushing strength, but the abrasion resistance is a little bit decreased. Longgu fat coal can be considered as the main coal in coal blending constitution, and its place of origin can be taken as the base of coal resource.
