青龙煤矿煤系沉积环境及煤质变化规律浅析

Analysis on Sedimentary Environment of Coal Measures and Change Law of Coal Quality in Qinglong Coal Mine

青龙煤矿煤系地层为二叠系龙潭组,本文以青龙煤矿勘探钻孔及生产揭露资料为基础,对该区煤系地层沉积环境及煤质进行了分析,简述了本区煤系地层为一套海陆交互相、多旋迥沉积体系。通过对煤中灰分、硫分、挥发分等煤质特征的分析研究,还原了各煤层的沉积环境和变化规律的原因,为今后煤矿开采、利用提供了借鉴和依据。

The coal measures strata in Qinglong Coal Mine are the Permian Longtan Formation. Based on the data of exploration boreholes and production exposure in Qinglong Coal Mine, the sedimentary environment and coal quality of the coal measures strata in this area are analyzed. According to the analysis and study of coal quality characteristics such as ash, sulfur and volatile matter, the coal seams are reduced. The depositional environment and the causes of the change law are discovered, which provides a reference and a basis for coal mining and utilization in the future.
