抚顺煤田生成于新生代第三纪,是世界上闻名的特厚煤层之一。煤层走向大致东西,南北顿斜,南翼煤层倾角近似30度,北翼为逆掩断层所切,倾角35～60度。煤层分为五个自然分层,厚度很大,变化剧烈,全区均可采。西部3、4、5三个分层较稳定;东部1、2、3三个分层间无明显夹矸石存在,合为一层。西部煤层 Fushun Coalfield was formed in the Cenozoic Tertiary, is one of the world famous thick coal seam. The coal seam runs roughly to the east and west, and the north and south are inclined obliquely. The coal seam dip in the south wing is approximately 30 degrees, and the north wing is cut in the reverse cover of the fault, with an inclination of 35-60 degrees. Seam divided into five natural stratification, thickness, dramatic changes, the region can be adopted. 3, 4 and 5 western strata are more stable; there is no obvious gangue in the east and west of 1, 2 and 3 stratification.
