河南省赋煤单元划分及控煤构造模式分析

Coal-hosting Units Division and Coal-controlling Structural Mode Analysis in Henan Province

河南省在大地构造位置上跨越华北板块、秦岭-大别造山带两个重要构造单元,是华北聚煤域的重要组成部分,由于特殊的构造位置,使得河南省煤田构造格局具有南北分带、东西分区的基本特征。结合地层(含煤地层)沉积特征和煤层赋存状况分析,将河南省赋煤单元划分为太行赋煤构造带、嵩箕赋煤构造带、崤熊赋煤构造带和秦大赋煤构造带,各赋煤构造带可进一步划分为2个赋煤构造亚带。根据区内构造发育特征,控煤构造模式可分为5大类17小类,其中滑动构造、逆冲叠瓦构造、伸展构造及同沉积构造4种控煤构造样式为河南省煤田典型控煤构造模式。

The geotectonic situation of the Henan Province is spanning across the North China plate and Qinling-Dabie orogenic belt two important tectonic units, thus a major integral part of North China coal-accumulation regime. Since its special structural setting, makes coalfield structural configuration in the province with basic feature of NS zoning and EW districting. Combined with strata （coal-bearing strata） depositional features and coal seam hosting analyses, divided the coal hosting units into Taihang, Songshan-Jishan, Xiaoshan-Xionger and Qinling-Dabie coal-hosting structural zones, and every zone can be further divided into 2 subzones. Based on structural development features, coal-controlling structural mode can divide structures in the area into 5 groups and 17 kinds, in which, four coal-controlling tectonic patterns of gliding tectonics, thrusting imbricate structure, extensional tectonics and svndepositional structure are the typical coal-controlling structural modes of Henan coalfields.
