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。

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 low-ering from northeast to southwest, while coal No.4 presents relatively high in southwest. Forms of sulfur are mainly sulfide sulfur, sedi-mentary 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.
