,开展煤层赋存规律及变化原因研究,就显得十分必和迫切.本文以群英聚煤区内的钻探、物探等相关资料为依据,以煤田地质、构造地质、沉积岩与沉积相等理论为指导,对群英聚煤区的地质构造、煤系沉积特征、煤层煤质等进行总结和归纳,探讨了煤层形成条件及赋存特征.并通过主采煤层的厚度分析,总结得出如下煤层厚度变化规律：
(1) 3#煤层总厚度变化在3.45～5.89m,平均4.67m,连续性好,全区分布,总体上厚度聚煤区东南部较大,由东南向北西变薄,变化规律明显.该煤层含夹矸0-2层,属结构简单,并易于对比的煤层,属较稳定煤层.
(2) 11#煤层厚度1.27－4.51m,平均2.89m,连续性好,全区分布.聚煤区东南部和西部,煤层厚度较大,均在2m以上,向北煤层分岔（11下煤层）,显示该煤层向北有可能演变为2个分层.总体上属厚度变化稍大的较稳定煤层.
(3)分析了影响煤层厚度变化的因素主要有以下几个：影响3#和11#煤层厚度变化的因素主要有沉积环境、沼泽基底不均衡沉降,河流同期冲刷、后期构造变动和沉积基底不平.

In coal seam, mineralizing rules and reasons for such changes and study, appear very will and urgent. In this paper, the area of west coal-accumulating drilling, geophysical exploration and other related material as the basis, geology, with structural geology, sedimentary and sedimentary equal theory, the west to gather the coal geological structure, sedimentary characteristics of the coal seam coal, summarizes and induced, and discusses the formation conditions and occurrence characteristics of coal seam. And through the main CaiMeiCeng, analysis the thickness of the coal thickness variation law that are as follows:
(1) 3 # coal seam thickness of total change in 3.45 ~ 5.89 m, an average of 4.67 m, continuity, the distribution, the overall thickness coal-accumulating southeast area is larger, the southeast to the north west become thinner, and change rule obvious. The coal gangue containing clip 0-2 layer, simple structure and easy to of coal seam, the contrast of a stable coal seam.
(2) 11 # coal thickness 1.27 4.51 m, an average of 2.89 m, continuity, the distribution. Coal-accumulating area southeast and the west, thickness of coal seam are larger, more than 2 m in the north, coal seam bifurcation (11), shows that the lower coal seam to north may develop for two stratification. In general the thickness of the coal seam slightly more stable.
(3) analysis of the influence of the coal thickness changes are the major factors that affect the following several # 3 and 11 # coal thickness changes are the major factors of sedimentary environment, swamp basal imbalance, in the same period, scouring rivers settlement later structure change and sedimentary base uneven.
