高家庄煤矿太原组煤层特征分析

The Taiyuan Formation and Its Coal Beds in the Gaojiazhuang Coal Mine

根据研究区大量钻孔钻资料,太原组主要由三角洲平原相、三角洲前缘相及潮坪相构成,岩性以粉砂岩、细砂岩为主,夹生物碎屑灰岩、煤层等。通过研究发现,煤层主要赋存于太原组下部,其中主要可采煤层8号煤层属低灰、中—中高硫、中高—高发热量焦煤(瘦煤),9+10号煤层属低灰、低—中硫、中高—高发热量焦煤(瘦煤)。

The Taiyuan Formation in the Gaojiazhuang Coal Mine is composed of siltstone and fine sandstone intercalated bioclastic limestone and coal beds of delta plain, delta front and tidal flat facies. The coal beds are confined to the lower part of the Taiyuan Formation. The coal bed 8 as a main minable coal bed belongs to low-ash, medium-high-sulphur, medium high-high and calorific value of coking coal（lean coal）, while coal beds 9 and 10 belong to low-ash, low-medium-sulphur, medium high-high and high calorific value of coking coal（lean coal）.
