莱芜潘西煤矿降低高硫煤含硫量的几点措施

Countermeasures on Reducing Sulfur Content in High Sulfur Coal of Panxi Coal Mine in Laiwu City

摘要:

根据目前国内煤炭脱硫技术的发展现状，该文分析研究了潘西煤矿的煤质特征和硫的赋存状态特征。为了降低商品煤中的硫分，潘西煤矿采取了筛选和捡选原煤中黄铁矿结核降低商品煤硫分，上下组煤合理配采降低商品煤硫分，洗选法降低硫分等措施，使煤的质量明显提高，获得了较好的经济效益。

Abstract:

According to present condition of desulfurization technology in coal mine, characteristics of coal quality and sulfur occurrence characteristics of Panxi coal mine have been analyzed and studied in this paper. In order to reduce the sulfur content in commercial coal, some countermeasures are carried out, such as selecting and picking pyrite nodules, reasonable partition between upper and lower parts of coal, and washing coal to reduce sulfur content in commercial coal. Thus, the quality of coal has been improved significantly, and achieved a good economic benefit.
