摘要
为进一步探究煤尘云最低着火温度及其影响因素,分别选取规格为38~50、51~75、76~88、89~150μm的几类典型煤样,并通过控制变量,分别研究喷尘压力、煤尘粒径、挥发成分比例和惰性粉体添加量四种主要因素对煤尘云最低着火温度的影响,以期为今后的煤炭开采安全管理工作提供一定的参考借鉴。
In order to further explore the minimum ignition temperature and its influencing factors of coal dust clouds,specifications of 38~50,51~75,76~88,and 89~150μm were selected respectively.And by controlling variables,the effects of four main factors,namely spray pressure,coal dust particle size,volatile component ratio,and inert powder addition,on the minimum ignition temperature of coal dust clouds were studied,in order to provide certain reference for future coal mining safety management work.
