摘　　要：大同煤田位于山西省北部,主要含煤地层为石炭系太原组、二叠系山西组和侏罗系大同组。依据大同煤田构造发育特点,分析了区域构造对煤田构造格局的控制作用。研究认为,大同煤田主体为一向斜构造,控制了煤系的分布范围。区内控煤构造样式包括压缩构造和伸展构造两大类,前者分布于煤田边界,主要包括逆冲前锋构造、逆冲叠瓦构造、双冲构造、叠瓦扇构造等类型;后者主要分布在煤田内部,以正断层控制的堑垒构造类型为主,构成井田边界或采区边界。The Datong coalfield is located in the northern Shanxi Province;its major coal-bearing strata are Carboniferous Taiyuan Formation,Permian Shanxi Formation and Jurassic Datong Formation.Based on structural development features,analyzed tectonic controlling on coalfield structural framework.The study has considered that the principal part of the coalfield is a syncline,it controls coal measures distribution.Coal-control structural patterns include two categories of compression and extension structures;the former is distributed near the coalfield boundaries,mainly thrusting front,thrusting imbricate,duplex thrusting and imbricate fan-shaped structures;the later is distributed in the coalfield interior,mainly normal faulted grabens and horsts,and composing minefield or winning district boundaries.
