摘　　要：为了揭示团鱼山地区的煤田构造展布特征及其控煤效应,对近年来最新物探、钻探等地质资料进行了研究,在分析研究区内构造特征和构造演化过程的基础上,深入探讨控煤构造作用。研究结果表明:研究区构造对含煤地层改造影响强烈;由4个赋煤构造单元组成;构造类型有3种;控煤构造经历了5个演化阶段,各阶段控煤作用不同且相互影响。In order to figure out the structural distribution pattern of coalfield and their control effect in Tuanyushan area,through collecting and analyzing the latest geological data including geophysical prospecting,drilling and so on,this paper discussed the coal-controlling structure in depth,based on the analysis of the structure characteristics and tectonic evolution of study area. Results of research suggests： the structures make strong influence on coal-bearing strata transformation in Tuanyushan area; it can been divided into four coal occurrence tectonic units; there are three structural patterns of coal-controlled tectonic; the coal-controlling structures have experienced five stages,and structures of each stage control the coal bed and influence each other.
