Preparation of blended raw high-sulphur coal in Dongpang coal mine

There are abundant No.9 coal resources in Dongpang coal mine,most are high-sulphur gas-fat coal and fat coal,the caking property is excellent,so just reduce sulphur content,the blended raw coal can be used to coking.Investigate the coking properties of No.2 and No.9 coal resources according to coal blending test,coal quality analysis and 40 kg sample coke oven test.The maximum reflectance of vitrinite test show that,the blended coal retain some part of raw coal characteristics,its industrial natures and caking property can be solved for weighting function.The blended coal for cleaning can comprehensively utilize high and low sulphur coal resources.The newly-built Xipangjing coal preparation plant adopts the research achievement for practical production guidance,the middle and high sulphur gas-fat coal products meet the market demand,that means the benefits increase.The high sulphur clean coal yield is 1.11×106 tons,increase 1.5×108 yuan in 2011.
