贵州省大方县滴水岩煤矿硫分特征及沉积环境研究

Research on sulfur characteristic and sedimentary Environment of dishuiyan coal mine Guizhou dafang county

介绍了滴水岩矿区地质、含煤地层岩相组合、煤层及煤质特征等概况,对矿区各可采煤层的硫分分布规律进行统计及分析,并结合矿区黄铁矿赋存状态对该区煤矿的沉积环境进行讨论,指出区内可采煤层在成煤时处于与海水有关的三角洲、泻湖等泥炭沼泽环境。

This paper introduced the geology of Dishuiyan coalmine area,rock combination of coal-bearing strata and coal seam and coal quality characteristics overview,the statistics and analysis of each workable coal seam of the coalmine area were done as well,combining with the common pyrite occurrence status of this area,sedimentary environment was discussed,it was also indicated that when the coal was forming,this area was located in moss-land environment like delta and lagoon which were related to the sea.
