东北地区早白垩世炼焦煤矿区资源的煤质特征
Coal quality characteristics of Early Cretaceous coking coal mining resources in Northeast China
摘要
Abstract
The Mesozoic coking coal resources in China plays an important role in the domestic coking coal re-sources,the coking coal mining areas are mainly distributed in the eastern three leagues of Inner Mongolia and the three provinces of Heilongjiang in Northeast China,so it is necessary to study the coal quality characteristics of the Early Cretaceous coking coal mining areas.Based on the regional distribution characteristics of coking coal in China,the basic characteristics of the main coking coal mining areas in the Early Cretaceous of the Mesozoic era was intro-duced in the paper,and the distribution overview,coal bearing coal seams and geological reserves,coal quality characteristics of mining areas,and utilization pathways of Jixi and Hegang mines in Heilongjiang Province were mainly analyzed.Due to the complex and variable coal forming conditions in the Jixi mining area,the types of coking coal are mainly coking coal,1/3 coking coal and lean coal,as well as a small amount of gas coal and long flame coal,Xing'an mine is gas coal and Ronghua mine is long flame coal.Hegang mining area is one of the coking coal mines with large reserves in the Early Cretaceous in Heilongjiang Province,and the maximum thickness Y value of its gelatinous layer and the average maximum reflectivity of its vitrinite are lower than the other three mining areas,the coke quality of 1/3 coking coal in Hegang mining area is the lowest among the four mining areas,but its average sul-fur content is lower.When using the ultra-low sulfur coal of Hegang mining for coal blending coking,the sulfur con-tent of coke can be significantly reduced.The average degree of metamorphism of coal in Shuangyashan mining area is the shallowest,and the sulfur and ash content of coal in each mine are relatively low.The coal types in Lingdong and Lingxi mines are mainly 1/3 JM,and newly opened mines are mostly gas coal.The coal in the Qitaihe mining area has the highest degree of metamorphism,the coke quality of its 200 kg coking coal of Qitaihe mining areas is better,mainly consisting of coking coal and 1/3 JM,followed by a few mines with different metamorphic hard coal such as fat coal and a few lean coal.关键词
