摘　　要：提出了粉煤可压缩性定义，设计了粉煤侧限压缩实验方法．以晋城煤、古交煤和大同煤为对象，研究了外加压力、煤的变质程度、煤料含水量及粒度级配等因素对粉煤压缩率的影响．指出了粉煤可压缩性是影响其成型特性的主要因素之一，也是型煤生产中选择成型压力的重要依据．研究结果为型煤生产提供了理论基础．The compressibility of the coal is first defined, and the confined compression test method is presented. The effects of the extra force, the degree of metamorphism of coal, the moisture and the particle graduation of coal sample are studied on the compressibility coefficient of fine coal with the Jincheng coal, Gujiao coal and Datong coal. It is pointed out that the compressibility of fine coal is not only one of main factors influencing the briquettability of fine coal but also important basis selected briquetting force. This study supplies theoretical foundation of the briquette production.
