The coal bed of Qiongdongnan basin distributes mainly in Yacheng Formation of lower Oligocene. Ash contents of coal samples are 13.59%-58.33%, and of carbonaceous mudstone samples are 56.08%-81.33%. Minerals of the coal samples consist of clay, sulfides (pyrite) and quartz. Total sulfur contents of coal samples are 1.07%-6.39% and most of the samples are high-sulfur coal. All the coal samples are bituminous coal with 17.97%-33.53% volatile matter. Total organic contents are 61.7%-96.1% of the coal samples and 38.5%-59.8% of the carbonaceous mudstone samples. Vitrinite is the primary maceral with the content of 58.4%-98%;Inertinite accounts for 1.4%-3.5%, and almost no exinite exits. Vitrite of the coal samples is 46.7%-93.2% and of the carbonaceous mudstone samples is 18.2%-31.6%. Carbon content of the coal is lower with the minimum of 25.09% and the maximum of 65.60%, and less than that of bituminous coal because of the relative high contents of minerals, volatile matter and sulfur. The characteristics of coke button are adhesive, less adhesive and no molten coherence. Maximum vitrinite reflectance of the coal samples varies 1.04%-1.23% with the average value of 1.14%, indicating that the coal with relative high metamorphic stage between metabituminous and medium volatile bituminous coal, was bituminous of moderate metamorphic stage. The coal at the second coalification jump was good for tremendous gas expelling out, which is in favor of forming the gas reservoir of coal\|formed gas field under favorable conditions.
