摘　　要：晚二叠系龙潭组是川南主要含煤地层,其富煤带的形成、展布方向及排列上展现出一定的规律性,并受古构造、古地理等因数的影响。通过相邻矿段、井田的资源量丰度对比,分析了富煤带的变迁规律,分析矿段主要煤层厚度变化因素。The Upper Permian Longtan Formation （P3l） is the main coal-bearing formation in south Sichuan. The formation and distribution of coal-rich zone are controlled by paleostructure and paleogeography. This paper deals with factors of variation in thickness of coal beds of coal-rich zone in the Lianghe mine block, Guxu Mine Field.
