贵州省金沙县官田坝向斜煤炭整装勘查区煤质特征分析

Coal quality characteristics analysis of syncline coal consolidated survey area in Guantianba,Jinsha County,Guizhou province

通过对勘查区内煤炭勘探工程取得的大量基础性煤质资料进行整理及统计,系统分析了官田坝向斜煤炭整装勘查区内可采煤层的煤质特征情况,探讨了灰分、硫分在垂向上和平面上的变化规律,指出区内可采煤层从浅至深的其原煤平均灰分变化范围较小,可采煤层硫分变化较大,原煤硫分随深度增加逐渐增大。区内各可采煤层煤类均为无烟煤三号,结合勘查区内煤的工业用途评价可知,该煤可用于动力用煤、民用煤、火力发电、一般工业锅炉用煤、气化用煤等。

Through the collation and statistics of a large number of basic coal quality data obtained from coal exploration project in coal exploration area, this paper analyzed the coal quality, characteristics circumstances of workable coal seam in syncline coal consolidated survey area of Guantianba systematically, and discussed the change law of ash and sulfur on vertical direction and on plane, it is indicated that the ash content of workable coal seam does not change a lot with the increase of the depth, but the sulfur content changes a lot, generally speaking, the sulfur content increases with the increase of depth. The coal type from workable coal seam are all No. 3 anthracite in the area, combining with the industrial use evaluation of coal in the exploration area, we can see that the coal could be used as power coal, civil coat, thermal power generation coal, general industrial boilers coal and coal for gasification.
