结合潞宁煤的煤质特征，对其进行形貌分析、原子面扫描及扫描电镜表面结构分析。分析结果表明：潞宁煤为低硫、低灰、中高挥发分、特高热值、中等偏强黏结性煤；煤中的矿物质主要为粘土矿，主要成分为 Al、Si；煤的表面无明显裂隙和孔，断口呈植物管孢状结构明显，说明潞宁煤的变质程度较低；煤中均含有部分杂原子基团和芳香族化合物。
結閤潞寧煤的煤質特徵，對其進行形貌分析、原子麵掃描及掃描電鏡錶麵結構分析。分析結果錶明：潞寧煤為低硫、低灰、中高揮髮分、特高熱值、中等偏彊黏結性煤；煤中的礦物質主要為粘土礦，主要成分為 Al、Si；煤的錶麵無明顯裂隙和孔，斷口呈植物管孢狀結構明顯，說明潞寧煤的變質程度較低；煤中均含有部分雜原子基糰和芳香族化閤物。

Combining with the coal quality characteristics,the morphological analysis,atomic surface scan and surface structure analysis using scanning electron microscope were done for Luning coal.From the result we can see that:Luning coal is low sulfur,low ash,medium-high volatile matter,especially high calorific value and medium-relatively high caking property coal;mineral substance in coal is mainly the claymineral,main components are the Al and Si;the surface of the coal has no cracks and holes,the fracture is obviously the plant chamaesiphon fuscus structure,which means that the metamorphism degree of Luning coal is relatively low;the coal all has some heteroatom group and aromatic compounds.
