Cause and Distribution of Sulfur Content of the Zishan Coal in Tengtian Mining Area
摘要
基于藤田矿区地质资料进行综合分析研究
阐述梓山组煤中硫分特征
并对其成因进行分析。发现梓山中期海侵高潮时海水从西南方向浸漫至藤田
该期水体停滞所致的强还原条件是导致本区硫分形成的主要因素
另外煤层形成之后受到海相灰岩顶板影响使煤中硫含量增高且区内煤中硫分具有由西南至北东降低趋势。
Abstract
n this paper
characteristics of coal sulfur content for Zishan mountain group was expounded and its causes were analyzed based on a comprehensive analysis of Tengtian mine geological data.Analysis found that seawater soaked into Tengtian form southwest in the middle height of Zishan when strong sea tide came
thus strong reducing conditions caused by remained seawater became the main factor to the formation of coal sulfur content
meanwhile increase of sulfur content and it’s decrease distribution from southwest to northeast was caused by influence of marine limestone roof while coal was formed.
