构造煤是煤矿瓦斯灾害防治和煤层气开发的重要研究内容之一,根据对华北板块区域构造及构造煤分布规律的研究,构造煤的区域分布主要受构造控制,其中,构造煤最发育的区域是豫西滑动构造区;其次是挤压褶皱和推覆构造区,包括华北板块南缘的徐宿推覆构造分区、淮南构造分区、平顶山构造分区、板块北缘构造区和鄂尔多斯盆地西缘构造分区;再次是板块中带构造区和板块南缘永城构造分区,构造煤主要形成在盆地或隆起的边缘断裂构造两盘。在地质历史演化过程中,构造煤主要是在先期构造应力场作用下形成的,后期构造应力场作用居于次要地位。
According to the study on the regional structure of tectonic coal and the distribution of tectonic coal in North China, the regional distribution of tectonized coal is mainly controlled by tectonics. Among them, the most developed area of tectonized coal Is the western Henan slip tectonic zone, followed by the compressive fold and nappe tectonic zones, including the Xujian nappe structure zone, the Huainan structural zone, the Pingdingshan tectonic zone, the northern margin of the plate and the western margin of the Ordos Basin Zoning; again, the tectonic zone in the plate zone and the Yongcheng tectonic zone on the southern margin of the plate tectonic coal are mainly formed in the basin or uplifted edge of the fault structure two sets. During the geological history, tectonic coal was formed mainly in the early tectonic stress field, and later tectonic stress field was in a secondary position.
