摘　　要：对贵州省赫章县罗洲勘查区龙潭组含煤层的含煤性及可采煤层进行了分析总结,结论显示,赫章县罗洲煤炭勘查区含煤岩系(龙潭组)属海陆交互相及陆相沉积,地层平均厚度218.63 m,含煤6~22层,一般为15层,煤层总厚度5.18 m^13.94 m,平均9.90 m,含煤系数4.52%;含可采煤层5层,可采总厚度2.76 m^12.36 m,平均6.23 m,可采系数2.85%。该结论对该区今后的勘查工作具有借鉴、参考作用,可达到以最少的勘查投入获得最大效益的目的。This paper analyzes and sums up the coal-bearing properties and minable seams of Longtan formation？ stratum in Luozhou coal exploration area of Hezhang County of Guizhou Province, the conclusions of which show that the coal-bearing series （Longtan formation）in Luozhou coal exploration area of Hezhang County belongs to interactive marine and terrestrial deposit and terrestrial deposit with the formation average thickness of 218.63 m, 6～22 coal-bearing seams （usually 15 ）, total seam thickness of 5.18 m～13.94 m （average of 9.90 m）, and coal-bearing ratio of 4.52%; contains 5 minable seams with total ruinable thickness of 2.76 m～12.36 m （average of 6.23 m） and mining？coefficient of 2.85%. The conclusions have a reference value to the exploration work in this area in the future.
