| 摘 要： | 根据地质勘探资料和煤心煤样的分析结果,对贵州金沙安洛区北段煤中硫的时空分布以及煤中硫与沉积环境的关系进行了研究。结果表明,该区形成于以潮坪为主的过渡相环境,由于沉积过程中受海水影响,煤中硫的质量分数总体偏高;但由于海水对煤层作用的强度不一,使不同煤层或同一煤层不同部位硫的质量分数差异很大,而且煤中硫的质量分数变化与煤层顶底板的古地理环境有关。

| Abstract: | Based on geologic field exploration data and labor coal core measurement data the sulfur contents and distribution in coals as well as the relationship with the depositional environment in the northern section of Anluo exploration area,Guizhou Province are discussed.The results indicated that the coals in study area formed in a tide flat environment,as a result of seawater influence,the content of sulfur in coals is rather high.Meanwhile,due to different degree of seawater influence the content of sulfur in coal seams are different,and varied from one part to another part of same coal seam.In addition,the changes of sulfur content are related to palaeo-geographic environments of surrounding rock formations. |
