| 摘 要： | 重庆地区须家河组为一套砂岩、泥岩、砂质泥岩、粉砂岩和煤层组成的湖滨-三角洲型沉积,煤质分级主要为中灰（特低灰-高灰）、低硫（特低硫-中高硫）、高热值（低热值-特高热值）煤;灰分与硫分等值线分布较为相似,总趋势为北东-南西向展布,呈不规则条带状和团块状分布;原煤灰分值与发热量值呈负相关性,浮煤灰分值与发热量值呈正相关性,初步得出同一采集点原煤和浮煤的灰分与发热量的相关性正好相反,煤类分布与挥发分等值线展布相似的结论。

| Abstract: | The Xujiahe Formation in the Chongqing area is a set of sandstone,mudstone,sandy mudstone,siltstone and coal seams composed lacustrine shore-deltaic deposit.Coal quality is mainly medium ash(extra-low to high ash),low sulphur(extra-low to medium-high sulphur),high heat value(low to extra-high heat value) coal.Isolines of ash and sulphur contents are similar,main trend NE-SW extending,present irregular banded and massive distribution.Raw coal ash contents and calorific values present negative correlation;whi... |
