摘要 综合利用金刚煤矿矿区地表勘查成果、深部钻孔等资料,总结了矿区浅部、深部构造特征,并分析了矿区煤层物性特征及煤质特征。研究表明:①矿区主要的含煤层位为上三叠统须家河组第五段(T3xi5)及第七段(T3xj7),且须家河组第七段(T3xj7)为矿区最主要的含煤层位;②矿区煤层以亮煤为主,暗煤次之;③区内煤层原煤水分平均小于0.9,挥发分(Vdaf)产率平均为29.04%~33.36%,CO2含量不超过2%,煤层折算后的平均硫分含量较折算前的硫分降低0.17%~0.19%,浮煤全硫脱硫率为67%,脱硫效果中等。

Abstract: Based on the surface exploration data and deep drilling results of Jingang coal mining area,structural characteristics of shallow and deep area of the mining area is summarized,and coalseam) physical property and coal quality characteristics in the mining area are also discussed.The study results show that:①main coal-bearing strata in the mining area are the fifthT3xj5) and seventhT3xj7) segment of Upper Triassic Xujiahe Group,and the seventh segmentT3xj7) of Xujiahe Group is primary coal-bearing strata in the mining area;②the coal seam in the area is mainly for bright coal,and followed by dark coal;③the average water content of coal seam is less than 0.9,average of Vdaf is 29.04%~33.36%,content of CO2 is not more than 2%,and the average sulfur content of coal seam is lower than that of 0.17%~0.19%, the sulfur desulfurization rate of floating coal is 67% and the desulfurization effect is medium.
