选取彬长矿区典型低阶煤样开展煤质微表面形貌特征分析,分别进行粉尘粒径分布试验、矿物组分分析试验、煤尘微观特征试验及粉尘接触角测定,分析低阶煤微表面形貌特征对其润湿性影响特征。试验结果表明:岩尘粒径整体大于煤尘粒径,煤样表面粗糙且孔隙多,矿物质成分以石英和高岭石为主,石英是氧化物类原生矿物,润湿性较好;高岭石是黏土类矿物,润湿性较差,试验低阶煤样均为疏水性粉尘。

Typical low rank coal samples in Binchang mining area were selected to analyze the microscopic characteristics of coal quality, dust particle size distribution test, coal dust microscopic characteristics test, dust composition analysis test and dust contact angle measurement were carried out respectively, the influence of micro-surface morphology characteristics of low rank coal on its wettability was analyzed. The test results show that the particle size of rock dust is larger than that of coal dust, and the surface of coal sample is rough and has many pores, the mineral components are mainly quartz and kaolinite. Quartz is an oxide primary mineral with good wettability. Kaolinite is a clay mineral with poor wettability, the low rank coal samples in the test are hydrophobic dust.
