摘　　要：选择具有代表性的高硫煤(山东兖州煤与重庆南桐煤)为研究对象,通过深度解离(-200目以下),采用红外光谱、X-射线衍射、电子能谱仪、扫描电镜等表征手段对两种煤中煤和黄铁矿硫的物理性质、矿物成分及解离面的表面化学组成、界面物理化学特性差异进行分析。研究揭示高硫煤在高解离度下煤与煤系黄铁矿硫的物理特性、表面特性、煤与煤系黄铁矿硫表面特性的差异.The paper researches on the typical high sulfur coals from Shangdong-Yanzhou Coal Mine and Chongqing-Nantong Coal Mine. The physical characteristics, mineral components, chemical components on sides separated less than 200 mesh and the differences of their interface physical and chemical charac- teristics of coals and pyrite sulfur in sample coals were studied by the means of Fourier Transform Infrared （FTIR） Spectrometry, X-ray Diffraction ,Electron Energy Spectral-Mete r（EDS） and Scanning E-lectron Mirror （SEM）. The research disclosed the physical properties and interface characteristics of coal and coal-derived pyrite sulfur deeply seperated and their differences.
