六盘水煤田是贵州的主要产煤区之一，地处黔南坳陷六盘水断坳内，含煤地层主要为上二叠统龙潭组、长兴组，含煤层数多、厚度大，含煤性由中部向西北、南东方向逐渐变差。区内含煤地层的发育主要与含煤岩系基底构造和成煤期岩相古地理有关，晚二叠世早期西部峨眉山玄武岩喷发对含煤岩系基底起到填平补齐作用。盘县-水城古断裂控制着陆相与过渡相的分界，进而控制着两侧含煤地层的含煤性，沉积古地理自西向东由陆相逐渐向海陆交互相过渡，盘县、水城一带聚煤中心为多期次聚煤作用叠加所致。由聚煤中心向西北（陆相）、东南（海相）方向，含煤性逐渐变差。
六盤水煤田是貴州的主要產煤區之一，地處黔南坳陷六盤水斷坳內，含煤地層主要為上二疊統龍潭組、長興組，含煤層數多、厚度大，含煤性由中部嚮西北、南東方嚮逐漸變差。區內含煤地層的髮育主要與含煤巖繫基底構造和成煤期巖相古地理有關，晚二疊世早期西部峨眉山玄武巖噴髮對含煤巖繫基底起到填平補齊作用。盤縣-水城古斷裂控製著陸相與過渡相的分界，進而控製著兩側含煤地層的含煤性，沉積古地理自西嚮東由陸相逐漸嚮海陸交互相過渡，盤縣、水城一帶聚煤中心為多期次聚煤作用疊加所緻。由聚煤中心嚮西北（陸相）、東南（海相）方嚮，含煤性逐漸變差。

The Lupanshui coalfield is one of major coal producing areas in Guizhou. Coal-bearing strata are mainly upper Permian Longtan and Changxing formations with many coal seams and large thickness;coal-bearing property gradually degraded from middle part to northwest, southeast directions. Coal-bearing strata development in the area was mainly related to the coal-bearing strata base-ment structure and lithofacies, paleogeography during coal-forming age. The eruption of the Emeishan basalt in west part during earlier Late Permian Epoch had helped the leveling of coal-bearing strata basement. The Panxian-Shuicheng paleofault controlled the bound-ary between continental facies and transitional facies, and then controlled coal-bearing property of strata both sides, Sedimentary paleo-geography from west to east transited from continental facies to marine-continental alternating facies. From coal-accumulation center to northwest (continental facies), southeast (marine facies) coal-bearing property is gradually poorer.
