对乌达矿区高硫煤层的沉积相、煤相和煤中硫在平面上的分布进行了研究。结果表明 ,1 0煤层泥炭聚积时的古水系对煤中硫的分布有明显的影响 ,9煤层泥炭聚积时的古环境决定了煤中硫的分布 ,浅水陆棚或分流间湾环境中形成的煤层具有较高 GI、V/ I值和硫含量 ,在障壁砂坝中形成的煤层具有高的硫含量、低的 GI、V/ I值 ,在泻湖中具有高 GI、V/ I值和相对较少的硫含量。 The sedimentary facies of the high-sulfur coal seam in Wuda mining area, the distribution of sulfur in the coal phase and coal in the plane were studied. The results show that the paleo-water systems during the accumulation of 10 peat coal layers have a significant effect on the distribution of sulfur in the coal. The paleoenvironment of peat accumulation in 9 coal seam determines the distribution of sulfur in coal, formation in shallow-water shelf or shunt bay environment The coal seam has high GI, V / I and sulfur content. The coal seam formed in the barrier bar has high sulfur content, low GI and V / I values, high GI and V / I values ​​in the lagoon and relative Less sulfur content.
