昭通聚煤盆地,南北长20公里,东西宽15公里,面积230平方公里。含煤地层时代为上新世晚期,含巨厚煤层,是我国特大型褐煤田。深入研究它的形成特点,对成煤理论、聚煤盆地的成因分类,对认识云南其他含有巨厚煤层的第三纪聚煤盆地的成因以及指导找矿勘探具有重要意义。
Zhaotong coal basin, 20 km long from north to south, east-west width of 15 km, an area of 230 square kilometers. The age of coal-bearing strata was Late Pliocene, with huge thick coal seam, which is an extra large brown coal field in China. It is of great significance to study the formation characteristics of coal-forming theory and the genesis classification of coal-bearing basins in order to know the origin of the Tertiary Poly-coal Basin with other thick and thick coal seams in Yunnan and to guide exploration and prospecting.
