攸县兰村矿区深部勘查区位于郴耒煤田北部，含煤地层二叠系上统龙潭组含煤层数较多且结构复杂，通过岩性特征、物性特征以及煤层特征等分析，基本查明了研究区煤层的赋存特征。结果显示：龙潭组上段1、2、6、9煤层为大部分可采不稳定煤层，3、4、5、7煤层为局部可采不稳定煤层，8、10、11、12煤层为不可采煤层；龙潭组下段含煤13～16层，只有16煤层在柳树冲区段大部分可采，为不稳定煤层。煤层可采范围的确定，为煤炭资源科学规划、合理开发及矿井安全提供了地质依据。

The Lancun deep part exploration area is situated in the north part of the Chenlei coalfield. Coal-bearing strata belong to up-per Permian Longtan Formation, with multiple structurally complex coal seams. Through analyses of lithological, physical and coal seam characteristics, basically identified coal seams hosting features in study area. The result has shown:in the upper member of Long-tan Formation, Nos.1, 2, 6 and 9 coal seams are mostly mineable unsteady coal seams, Nos.3, 4, 5 and 7 locally mineable unsteady coal seams, Nos.8, 10, 11 and 12 not mineable coal seams;in lower member of Longtan Formation have 13~16 coal seams, only the No.16 coal seam is mostly mineable in the Liushuchong sector and unsteady. The confirmation of mineable range of coal seams has provided geological basis for coal resource scientific planning, rational exploitation and coalmine safety.
