我国高硫煤蕴藏量不但很多,而且可采煤层占的比例很大。我国煤田开发中多选择浅部煤层和低硫煤层开采,高硫煤层尽量少采或者不采。随着工业发展和煤炭的大量开发和利用,我国不少煤矿已转入深部高硫煤层,尤其南方缺煤地区,高硫煤的开发比例更大。因此每年生产的煤炭含硫量不断地在增加,燃煤生成的二氧化硫量对环境的危害也越来越大。这样就给我们提出一个问题,如何减少烧煤对环境的污染和回收煤中硫化铁资源成为我国煤炭工业一大课题。一、我国高硫煤田的分布和开采概况 Not only is there a lot of reserves of high-sulfur coal in our country, but also a large proportion of coal seams can be taken. In coalfield development in our country, the shallow coal seam and the low-sulfur coal seam are mostly chosen to be exploited. The high-sulfur seam should be less or not taken as much as possible. With the development of industry and the massive exploitation and utilization of coal, many coal mines in our country have been transferred to deep high-sulfur coal seams, especially in the areas lacking coal in the south, with a higher proportion of high-sulfur coal being exploited. Therefore, the annual sulfur content of coal produced continuously increases, and the amount of sulfur dioxide generated from coal combustion is more and more harmful to the environment. This will give us a question, how to reduce coal pollution on the environment and recycling of iron sulfide resources has become a major issue of China’s coal industry. First, the distribution and exploitation of high-sulfur coal in China
