摘　　要：为定性研究无烟煤共伴生型微晶石墨,以内蒙古高变质无烟煤为对象,经超细粉碎、混酸脱灰处理,采用X射线衍射法、拉曼光谱法研究了试验样与不同变质程度无烟煤、鳞片石墨的拉曼特征参数。结果表明:通过试验样拉曼光谱特征参数比对可知,试验样应为无烟煤伴生微晶石墨,其拉曼特征参数:D峰频移为1330 cm^(-1)附近、G峰拉曼频移1590~1599 cm-1附近,R值小于1;石墨化程度愈高,AD/AG值和R值愈小。Taking high metamorphic anthracite as research object,the qualitative analysis of symbiotic amorphous graphite and anthracite was studied. Using X-ray diffraction to analysis the composition of ultrafinly pulverized and acid impregnated amorphous graphite based anthracite,and Raman spectra parameter change regulation of different anthracite and crystalline graphite were studied. The results showed that for acid impregnated amorphous graphite based anthracite, through Raman spectrum characteristic parameter comparison of experimental sample,the test sample should be microcrystalline graphite associated with high metamorphosed anthracite,its D band is about 1330 cm-1,G band is about1590-1599 cm-1,R value is less than 1,and the higher graphitization degree,the less the AD/ AGvalue and R value.
