Characteristic analysis and comparison of coking coal in Liliu area and Gujiao area of Shanxi Province and Mongolia
The distribution of coking coal resources in Shanxi and Mongolia was introduced.In order to address the shortage of domestic coking coal resources,explore high-quality coking coal resources abroad and provide stable and sustainable raw material guarantees for the domestic coal coke steel industry chain,the coal quality characteristics and coking characteristics of Mongolia coking coal,Shanjiao extra-strong Jiaojing 1#in Liliu area of Shanxi Province and Shanjiao extra-strong Jiaojing 2#in Gujiao area of Shanxi Province were compared and analyzed.The results showed that Mongolia coking coal had low degree of coalification,high content of active substances,easily oxidized and low sulfur content.The quality index of Mongolia coking coal was basically equivalent to that of ordinary coking coal in China.A certain amount of Mongolia coking coal with low sulfur content could be blended into Shanxi coking coal,so as to adjust the sulfur content of feed coal,which could be used as a supplement to the scarce coking coal resources in China.
