以水分、灰分、挥发分、发热量、硫分等为指标,分析了黔东北地区上二叠统吴家坪组C1煤层煤质特征,结果表明:其煤类以瘦煤为主,含少量的焦煤、无烟煤3号;属中灰、低挥发分、中等固定碳、中热值煤;灰成分以SiO_2、Al_2O_3、Fe_2O_3、CaO为主,具有低度沾污;工业用途为动力用煤、民用煤、火力发电、一般工业锅炉用煤;煤中的有害元素以S、F、As为主。
Based on the indexes of moisture, ash, volatile, calorific value and sulfur, the characteristics of C1 coal seam in Upper Permian Wujiaping Formation in northeast Guizhou Province are analyzed. The results show that the coal is dominated by lean coal with a small amount of coking coal , Anthracite No.3; belong to medium-ash, low-volatile, medium-fixed carbon, medium-calorific value coal; the ash content is mainly SiO_2, Al_2O_3, Fe_2O_3, CaO with low degree of contamination; industrial use as power coal, civilian coal , Thermal power generation, general industrial boiler coal; harmful elements in coal to S, F, As based.
