This paper takes Jingyuan Coal Power Ltd., Co.of Gansu as an example and analyzes the contents of water, dust, volatile components and carbon in different kinds of coals, and calculates the volatile components.It provides a basis for coal-dust explosion research and prevention by analyzing the relevant diameter, concentration and ignition energy.%以甘肃靖远煤电股份有限公司下属矿井不同变质程度的煤样为例,通过煤质分析测量不同煤质内水分、灰分、挥发分和固定碳的含量,计算其挥发分并对不同煤样进行煤尘爆炸试验,分析爆炸相关的粒径、浓度、点火能量等参数,可为煤尘抑爆措施研究和煤尘爆炸事故的防治提供依据.
