LIU Shan-de
Abstract：Based on the raw data of LYL exploration area exploration report in Yong-Long mining area,the basic characteristics of coal quality in main coal seams such as No. 2,2 -3 and 3 coal seam,were narrated. At the same time,the coal forming environment factors which led to coal quality difference were analyzed.The analysis shows that,No.2 and No.2 -3 coal are mainly semidull coal and dull coal,No.3 coal is mainly semibright coal and semidull coal.The main coal seams are all in low rank bituminous coal stage,the maceral is mainly vitrinite;the ash content is low- medium and the main component of ash content is acidic oxide,continental facies coal forming are indicated by coal facies ;the coal in this area is mainly the low-especially low sulfur coal,iron sulfide sulfur is the main sulfur existing way,after the flotation of sulfur,the separation and degradation effect are significant;the differences of coal forming environment are closely related to the change of coal quality.
