Abstract The coal samples in the No. 5 coal seam drilling in the Long South-East basin were analyzed with the methods of maceral analysis, proximate analysis and the analysis of the microelement were given. The results showed that there was close relation between Gallium and ash content. Gallium positively related to Al2 O3 and SiO2, were affected by terrigenous clast and major parts found in clay minerals. The arsenic increased with total sulfur , and mainly existed in the organic combination state. Phosphorus was given priority to with inorganic state, and was related with the total sulfur and arsenic content in coal
