摘　　要：邢东矿井位于太行山隆起带与华北沉陷带的过渡带,通过区域构造应力—应变场分析,本区先后经历了由挤压—拉张的变形过程,变形强度由弱到强。海西期构造应力影响较弱,印支期—中燕山期构造应力作用较为强烈,形成了大量的挤压结构面和压缩构造,燕山晚期—喜山期是构造形成的最终阶段,以拉张伸展变形为主,现今的多数正断层的断裂结构面仍保存有先期的挤压结构面特征。区内构造以断裂构造为主要形式,断层组合形式多样,这些构造形成期次不同,北西向断裂对北东向断裂具有限制作用。The Xingdong coalmine is situated in the intermediate zone between the Taihangshan uplift zone and North China subsidence zone. The area has experienced a compression-extension process, deformation strength from weak to strong, based on tectonic stress-strain field analysis. Impact from the Hercynian tectonic stress was rather weak and from the Indo-China-middle Yanshanian stage stronger, while the late Yanshanian-Himalayan stage was structural formation finalizing phase, mainly extensional deformation. Previous compressive structural plane characteristics are still preserved in structural planes of most normal faults at present. Structures in the area are mainly faulted structures, fault combinations are diversified, they were formed in different stages, and the NW faults have limited the NE faults.
