贵州黔西煤田白岩脚矿区煤中硫的分布规律

通过对黔西煤田白岩脚矿区龙潭组主要煤层进行化验分析,认为矿区煤中硫含量从低到高均有分布,垂向上自下而上逐渐降低,平面上9、14及15煤总体呈现东北部高西南部低的趋势,4煤层则表现为西南部相对较高;硫的赋存形态以硫化物硫为主,沉积环境控制了煤中硫的含量及各种形态硫的分布;9、14煤层以硫化物硫为主,脱硫效果良好,15煤层以有机硫为主,脱硫效果一般。建议在矿山开发过程中对低硫煤和高硫煤进行配采。

Coal Sulfur Distribution Pattern in Baiyanjiao Mine Area,Qianxi Coalfield,Guizhou Province

Through testing and analysis of Longtan Formation main coal seams in Baiyanjiao mine area, Qianxi coalfield have found a wide range of coal sulfur content distribution; vertically, gradually lowering from top to bottom; horizontally, coal Nos.9, 14 and 15 lowering from northeast to southwest, while coal No.4 presents relatively high in southwest. Forms of sulfur are mainly sulfide sulfur, sedimentary environment controlled sulfur content and every kind of sulfur form. Sulfur in coal Nos.9 and 14 is mainly sulfide sulfur with good desulfurization effect; in coal No. 15 is mainly organic sulfur with common desulfurization. Proration extracting of low sulfur coal and high sulfur coal has been proposed during coalmine exploitation.
