贵州省金沙县官田坝向斜勘查区煤中硫元素的分析与评价

The sulfur in coal analysis and assessment of Guantianba Xiangxie coal exploration area in Jinsha county of Guizhou

介绍了官田坝向斜勘查区的概况,从可采煤层硫元素质量分级、可采煤层形态硫分析、硫分在垂向及水平面上的变化规律等方面进行勘查区煤中硫元素的分析与评价,指出区内煤类属无烟煤三号,煤中硫分以中高硫和高硫为主,中硫和低硫次之,原煤硫分以硫铁矿硫为主,可通过洗选或动力配煤降低勘查区煤中硫的含量。

This paper analyzed the general circumstance of Guantianba Xiangxie coal exploration area,from aspects such as quality classification of sulfur element of workable coal seam,morphological sulfur analysis of workable coal seam,sulfur changing law at vertical and horizontal plane,the analysis and evaluation of sulfur were done.The coal belonged to No.3anthracite（WY3）,the most coal was middle-high and high sulfur coal,followed by low-sulfur and middle-sulfur coal,the sulfur in raw coal was mainly the pyrite sulfur,it could be reduced by washing or steam coal blending.
